The lev­el of humid­i­ty in the room affects the well-being and con­di­tion of the per­son as a whole, and in addi­tion — the prop­er­ties of envi­ron­men­tal objects. To find out the exact para­me­ters of air humid­i­ty will allow a spe­cial device — a hygrom­e­ter. Such a device is use­ful both in every­day life, to main­tain an opti­mal micro­cli­mate, and in some indus­tri­al areas, for exam­ple, in ware­house com­plex­es, or dur­ing con­struc­tion work.

It should be not­ed that for the human body, the range from 45 to 60% is con­sid­ered ide­al for air humid­i­ty.

In order not to make a mis­take with the choice, it is nec­es­sary to study the main aspects that you should pay atten­tion to when choos­ing a mea­sur­ing device.

Hygrom­e­ters are:

  • Mechan­i­cal, which show data with an arrow. These devices are bud­get-priced, but they are slow to respond to changes and may show data with minor devi­a­tions.
  • Elec­tron­ic — all indi­ca­tors are dis­played on the score­board. They are more expen­sive, but they quick­ly respond to changes in humid­i­ty indi­ca­tors and give a clear­er result.

Accord­ing to the prin­ci­ple of oper­a­tion, cur­rent­ly pop­u­lar hygrom­e­ters are divid­ed into:

  • Hair, which at the heart of mea­sur­ing tech­nol­o­gy use the prop­er­ties of a human hair under the influ­ence of humid­i­ty to change their state. This rel­a­tive­ly inex­pen­sive tech­nol­o­gy is often used in mechan­i­cal mod­els.
  • Film — use all the same prop­er­ties of some syn­thet­ic fab­rics to change their state depend­ing on humid­i­ty and tem­per­a­ture.
  • Weight — it is based on hygro­scop­ic sub­stances that can active­ly absorb water from the air.
  • Con­den­sa­tion hygrom­e­ter — it cools the sur­face for mois­ture to set­tle. The rel­a­tive humid­i­ty dis­played on the dis­play is high­ly accu­rate.
  • Psy­chro­met­ric is based on com­par­ing the read­ings of sev­er­al ther­mome­ters, one of which is in a humid envi­ron­ment. The eval­u­a­tion of the result in such devices is car­ried out using a spe­cial table, which requires con­sid­er­able men­tal effort on the part of the user.

The body mate­r­i­al can be plas­tic, wood and iron. The lat­ter is char­ac­ter­ized by increased dura­bil­i­ty, while nat­ur­al mate­ri­als empha­size the high sta­tus of the own­er.

Principle of operation

Hygrom­e­ters are divid­ed into sev­er­al mod­els that are dif­fer­ent in struc­ture and prin­ci­ple of oper­a­tion:

  • weight;
  • hair;
  • film;
  • elec­trolyt­ic;
  • elec­tron­ic;
  • ceram­ic;
  • psy­chro­met­ric.

weight A hygrom­e­ter is a col­lec­tion of tubes filled with a spe­cial sub­stance that changes den­si­ty depend­ing on the sat­u­ra­tion of the air pass­ing through them with water.

Hair deter­mines the mois­ture coef­fi­cient based on the prop­er­ty of the hair to change its length from mois­ture, the device rep­re­sents a stretched fat-free hair (often horse) and a spe­cial scale.

Film mod­el — a spe­cial film that stretch­es from mois­ture and shrinks in its absence, accord­ing to the loca­tion of the cen­ter of the film, the amount of mois­ture in the room is deter­mined by means of an arrow con­nect­ed to it.

Elec­trolyt­ic the device works on the degree of dilu­tion of the elec­trolyte applied to the glass, tak­ing read­ings with an inter­nal device, the main draw­back of the mod­el is the depen­dence of read­ings on air tem­per­a­ture.

Elec­tron­ic hygrom­e­ters mea­sure opti­cal and elec­tri­cal mea­sure­ments, this mod­el is quite com­mon in stores.

ceram­ic the device oper­ates on the basis of the con­duc­tiv­i­ty change prop­er­ties of the ceram­ic mass removed by the device.

psy­cho­me­t­ric the mod­el looks like a ther­mome­ter with an addi­tion­al scale; a spe­cif­ic sub­stance is placed in the tube cav­i­ty, which changes its tem­per­a­ture depend­ing on the water con­tent in the air.

The best electronic hygrometers for an apartment

Elec­tron­ic hygrom­e­ters for liv­ing rooms have max­i­mum func­tion­al­i­ty and vis­i­bil­i­ty. Man­u­fac­tur­ers addi­tion­al­ly equip them with inter­nal and exter­nal ther­mome­ters, clocks, built-in mem­o­ry. Experts have iden­ti­fied sev­er­al high-qual­i­ty mod­els.

Testo 608-H1

The elec­tron­ic hygrom­e­ter Testo 608-H1 will help you mon­i­tor the micro­cli­mate in a room of an apart­ment or house. The Ger­man device allows you to con­trol not only the humid­i­ty lev­el in the range of 10–95%, but also the tem­per­a­ture (0 … + 50 ° C). The device dif­fers in inde­pen­dent work, as a cur­rent source the kro­ne bat­tery is used. Thanks to this, you can mon­i­tor the humid­i­ty and tem­per­a­ture in dif­fer­ent rooms. Humid­i­ty infor­ma­tion is dis­played in large num­bers at the top of the liq­uid crys­tal dis­play, tem­per­a­ture is indi­cat­ed in small­er print, but the read­ings are clear enough to be seen from afar. Experts gave the mod­el the first place in our rat­ing.

Users also note the high mea­sure­ment accu­ra­cy and large screen. The only draw­back of the hygrom­e­ter, they con­sid­er the high price.

The best mechanical hygrometers for the home

Most mechan­i­cal hygrom­e­ters for the home use the so-called hair method, which is based on the prop­er­ties of human hair to change its state depend­ing on the lev­el of mois­ture and ambi­ent tem­per­a­ture. In addi­tion, there are also “film” mod­els, which have a dense fab­ric as a basis, which clear­ly responds to changes in the water lev­el in the air. Such devices are more expen­sive than hair ana­logues, but are more sen­si­tive to fluc­tu­a­tions in indi­ca­tors.

Mechan­i­cal devices are often “sharp­ened” only for mea­sur­ing the lev­el of air humid­i­ty, but some­times there are also mod­els with a ther­mome­ter.

When choos­ing such devices, be sure to con­sid­er the man­u­fac­tur­er’s rec­om­men­da­tions for place­ment. This is impor­tant for accu­rate inter­pre­ta­tion of the result.

5 Glass appliance VIT‑1

The rat­ing is opened by the most bud­getary hygrom­e­ter in our selec­tion — the VIT‑1 mod­el from the domes­tic com­pa­ny Stek­lo­pri­bor. This is a psy­cho­me­t­ric type device that shows the tem­per­a­ture and humid­i­ty in the room.
The device is made of plas­tic in turquoise col­ors. The dimen­sions are quite com­pact — 32 cm wide and 12 cm high, the device will take up a min­i­mum of space. It is pro­vid­ed for wall mount­ing. The mea­sur­ing tem­per­a­ture range is from 0 to 25 °C. The ther­mome­ter has an alco­hol struc­ture, while the humid­i­ty mea­sur­ing instru­ment is based on the psy­cho­me­t­ric method. Toluene is used here as a ther­mo­met­ric liq­uid.

In addi­tion to the psy­cho­me­t­ric hygrom­e­ter itself, the basic equip­ment includes a wick, a feed­er and detailed instruc­tions for use.

Cus­tomers not­ed the rather high accu­ra­cy of tem­per­a­ture and humid­i­ty mea­sure­ments. Many were pleas­ant­ly sur­prised by the detailed instruc­tions and the avail­abil­i­ty of all the nec­es­sary doc­u­men­ta­tion con­firm­ing the qual­i­ty of the prod­uct. But, some com­plained about the com­plex cal­cu­la­tions of indi­ca­tors from the table.

4 Sawo 115-HA

The orig­i­nal hygrom­e­ter from Sawo in the form of a house with a round dial inside, is locat­ed on the fourth line of the rat­ing. It is note­wor­thy that the body of the prod­uct is made of nat­ur­al pine wood, which exudes a nat­ur­al aro­ma and gives pos­i­tive ener­gy to the room.
The width of the mod­el 115-HA is 165 cm, and the height is 185. The man­u­fac­tur­er posi­tions its device as an excel­lent prod­uct for mea­sur­ing the mois­ture lev­el in a steam room, a bath. At the same time, the mea­sur­ing scale in the form of a round dial with black arrows will show fluc­tu­a­tions in val­ues ​​from 0 to 100%. The device is man­u­fac­tured in the Philip­pines, the man­u­fac­tur­er gives a 3‑year war­ran­ty for the prod­uct for mea­sur­ing humid­i­ty. Addi­tion­al­ly, it is pos­si­ble to buy a ther­mome­ter in the same style, thus assem­bling the orig­i­nal set.

Cus­tomers are gen­er­al­ly sat­is­fied with the qual­i­ty of the orig­i­nal Sawo hygrom­e­ter. Many not­ed the high accu­ra­cy and the case made of nat­ur­al wood. Most of the respon­dents rat­ed the device as mul­ti­func­tion­al — for home and sauna. But, some were con­fused by the lack of glass to pro­tect the dial.


  • Unusu­al design.
  • High accu­ra­cy.
  • Ease of use.
  • Suit­able for home and bath.
  • Body made of nat­ur­al wood.

3 Boneco A7057

The top three hygrom­e­ters for the home are opened by the A7057 mod­el from Boneco. The com­pact device in a white plas­tic hous­ing can be wall-mount­ed. The diam­e­ter of the round base is 5 cm, so the device does not take up much space in the apart­ment.
It should be not­ed that the man­u­fac­tur­er is Ger­many, the humid­i­ty meter is of good build qual­i­ty and min­i­mal error. The mechan­i­cal device shows the humid­i­ty range from 20 to 100%. It is impor­tant to con­sid­er that the prod­uct focus­es on min­i­mum, not max­i­mum val­ues. At the same time, the A7057 mod­el is capa­ble of oper­at­ing at ambi­ent tem­per­a­tures up to 120 degrees Cel­sius. The para­me­ters opti­mal for the human body are high­light­ed in a spe­cial col­or, which great­ly sim­pli­fies the inter­pre­ta­tion of the indi­ca­tors.

Among those who have tried the Boneco home humid­i­ty meter, most were sat­is­fied with the qual­i­ty. Many liked the con­ve­nient inter­pre­ta­tion of the result, most buy­ers high­light­ed the com­pact size as an advan­tage. How­ev­er, there were those who com­plained about the frag­ile case.


  • Com­pact.
  • High­lights the opti­mal scale.
  • Easy inter­pre­ta­tion of the result.
  • Ger­man qual­i­ty.
  • No need to set up.


  • There are mea­sure­ment errors.

2 Harvia SAC92200

The sec­ond in the rank­ing of home humid­i­ty meters is the device from Harvia. The SAC92200 fea­tures high pre­ci­sion and a styl­ish, eco-friend­ly design.
A lacon­ic, light­weight case in the form of a round­ed square with a clear dial inside attracts atten­tion. The width of the wall of the device is 13 cm, so it takes up a min­i­mum of space on the table. The val­ue scale dis­plays a step of 10 units. The body is made of nat­ur­al birch, a char­ac­ter­is­tic red­dish-brown hue. The prin­ci­ple of oper­a­tion here is based on the hair method. The device from Harvia is able to mea­sure the ambi­ent humid­i­ty in the range from 0 to 100%. For max­i­mum reli­a­bil­i­ty of infor­ma­tion, the man­u­fac­tur­er rec­om­mends installing a hygrom­e­ter at a con­sid­er­able dis­tance from the front door and at least 1.5 meters from the floor.

Most own­ers of the SAC92200 have rat­ed it as the ide­al indoor humid­i­ty mea­sure­ment device. Users find the prod­uct to be quite accu­rate. And only a few not­ed incon­ve­nient the fact that the device must be cor­rect­ly installed, in accor­dance with the require­ments of the man­u­fac­tur­er.


  • Round­ed square shape.
  • Birch body.
  • Indi­ca­tors from 0 to 100%.
  • High accu­ra­cy.
  • avail­able result.


  • Requires prop­er place­ment in the room.

1 TFA 45.2033

The best mechan­i­cal hygrom­e­ter for the home is mod­el 45.2033 from the TFA brand. In addi­tion to assess­ing the lev­el of humid­i­ty, this device is able to dis­play addi­tion­al tem­per­a­ture read­ings on the score­board.
The mea­sur­ing device is made in the form of a cir­cle, ringed with brass mate­r­i­al, which gives resis­tance to mechan­i­cal dam­age and a long ser­vice life. Eval­u­at­ing the indi­ca­tors is as easy as shelling pears, an infor­ma­tive dial that has mark­ings for com­fort zones will help. Thus, the cor­rect inter­pre­ta­tion of the result becomes a tru­ly easy task that even a child can han­dle. The device from TFA informs about the lev­el of humid­i­ty from 0 to 100%, and the tem­per­a­ture in the room — from ‑15 to +55 °C. The prin­ci­ple of oper­a­tion is based on the prop­er­ties of syn­thet­ic hair to change its length under the influ­ence of mois­ture vapor. The prod­uct, with a diam­e­ter of 102 cm, is rec­om­mend­ed to be mount­ed on the wall.

Cus­tomers liked the ther­mo­hy­grom­e­ter 45.2033. It is praised for its infor­ma­tive indi­ca­tors, durable case and accu­rate results. Most appre­ci­at­ed the fact that no addi­tion­al bat­ter­ies are required here. Few, though, said that when sun­light hits, the data is dis­tort­ed.


  • Met­al body.
  • Attach­es to the wall.
  • Shows humid­i­ty and tem­per­a­ture.
  • Round dial.
  • The accu­ra­cy is pret­ty high.


  • Must be installed away from sun­light.

How to DIY

The eas­i­est way to make a hair hygrom­e­ter at home. You need to assem­ble a sim­ple design from a scale print­ed from the Inter­net, an arrow and a fat-free hair con­nect­ing the arrow and the sur­face of the scale. The hair, depend­ing on the humid­i­ty, changes its length and deflects the arrow to the required val­ue. The sec­ond option is to fix the hair at the base of the ver­ti­cal scale, pull it and throw it over the nail locat­ed above the scale, attach a light weight to the free end, stretch­ing, the hair low­ers the weight indi­cat­ing the val­ue on the scale.

What to look for when choosing

Hygrom­e­ters are pur­chased for var­i­ous appli­ca­tions: from ama­teur to pro­fes­sion­al, the main para­me­ters when choos­ing:

  1. Accu­ra­cy and mea­sure­ment range. It is pos­si­ble to main­tain a suit­able humid­i­ty in the room with rel­a­tive­ly inac­cu­rate indi­ca­tors (+ ‑2%). Pro­fes­sion­als should choose a mod­el with­out error.
  2. Dimen­sions and pow­er sys­tem. Wire­less com­pact devices are easy to install any­where in the apart­ment or on the street.
  3. Exter­nal design (col­or, style, mate­r­i­al). Here, choose indi­vid­u­al­ly, based on your pref­er­ences.
  4. Avail­abil­i­ty addi­tion­al fea­tures (tem­per­a­ture mea­sure­ment, clock, cal­en­dar) will be a great addi­tion to the device.

How to choose a quality hygrometer

  1. Hygrom­e­ter designs
    . Russ­ian chil­dren have been famil­iar with psy­chro­met­ric devices since their school days. They are high­ly accu­rate, but dif­fi­cult to deter­mine humid­i­ty. Mechan­i­cal devices look as sim­ple as pos­si­ble. They are autonomous in oper­a­tion, and it is con­ve­nient to take read­ings from a visu­al dial. Elec­tron­ic hygrom­e­ters are mul­ti­func­tion­al. Many of them allow you to mea­sure the tem­per­a­ture, some are equipped with a clock. But the oper­a­tion of such devices depends on a bat­tery or accu­mu­la­tor.
  2. Mea­sur­ing range
    . In liv­ing rooms, the lev­el of humid­i­ty drops sharply in the win­ter sea­son, when the heat­ing is turned on. You can mon­i­tor the micro­cli­mate in a chil­dren’s room or bed­room using a device that oper­ates in the range of 20–70%. Such a device is also suit­able for grow­ing indoor plants. But in wet rooms (baths, saunas, base­ments) a hygrom­e­ter with a scale of up to 100% is required.
  3. Accu­ra­cy
    . Rel­a­tive humid­i­ty meters are dis­tin­guished by their mea­sure­ment accu­ra­cy. For a sim­ple lay­man, we can rec­om­mend a hygrom­e­ter with a divi­sion of up to 2–3%. It may be a con­ven­tion­al mechan­i­cal device. When mea­sure­ment accu­ra­cy is impor­tant, it is bet­ter to choose a mod­el with a divi­sion val­ue of 1%. This lev­el can be pro­vid­ed by an elec­tron­ic device or a psy­chrom­e­ter.
  4. Design
    . Many poten­tial buy­ers want to choose not only a func­tion­al device, but also a styl­ish acces­so­ry that will fit into the inte­ri­or of the room. For a bath, most often choose mod­els with wood or stone fin­ish­es. In the liv­ing room, plas­tic prod­ucts will look har­mo­nious, and for a nurs­ery, the design in the form of a toy will be an ide­al option.

We have select­ed in our review the 10 best hygrom­e­ters. All of them are sold in the trade net­work of our coun­try. The rat­ing was com­piled tak­ing into account the opin­ion of the expert com­mu­ni­ty and feed­back from Russ­ian con­sumers.
