Chinyezi - mmodzi wa zinthu zazikulu chilengedwe zokhudza yosungiramo ndiponso pokonza a mitundu yosiyanasiyana a zipangizo kumalizira mankhwala. Choncho, chinyezi muyeso ndi ndondomeko singasiyanitsidwe mu kupanga lapansi. Panopa, madokotala ambiri amalangiza kusunga digiri chinyezi komanso kunyumba, monga kuwerenga chinyezi analembedwa ndi bwino, makamaka ana. Ndi bwino kukhalabe angapezeke uku mu chipinda pa mlingo wa 50-70%. Kudziwa chinyezi mpweya ntchito chipangizo wapadera - hygrometer kapena monga iwo ukutchedwa, ndi hygrometer.
Hygrometers kubwera mu osiyanasiyana, amene amasiyana mfundo. kusiyana ndi mtheradi, ndi tsitsi hygrometer hygrometer psychrometric. Palinso zipangizo, amene ntchito zachokera kudziwa mame mfundo. Zikuluzikulu ndi zofala kwambiri ntchito ndi hygrometer psychrometric. Timatha inu kuyeza osati mlingo wa chinyezi, komanso kutentha. Psychrometric hygrometer kudziwa chinyezi wachibale peresenti. Ndi chifukwa chimene lonse maphunziro chili ndi awiri capillary. M'munsi mwa wina wa capillary nsalu atakulungidwa chingwe kumapeto ndi adatchithisira mu botolo galasi. Botolo chinyezi pamaso kudziwa anathira madzi. Scale hygrometer ndi maphunziro amakhala Celsius. kayesedwe zachokera kusiyana kutentha mpweya akusonyeza "youma" ndi "chonyowa" capillary. Aliyense hygrometer psychrometric amadziwikanso okonzeka ndi tebulo limene kusiyana kuwerenga kutentha anatsimikiza chinyezi wachibale.
Pakuti kuyeza chinyezi mpweya hygrometer psychrometric akayiyike woongoka pa mlingo diso otere kuti kuwerenga ake anali olondola kwambiri, i.e., pafupi sanali kutenthetsa kapena akututuma mbali. botololo m'pofunika madzi. Muyenera kuonetsetsa kuti chingwe si pokhudzana ndi makoma a botololo. Ndiye muyenera kudikira mpaka kusiyana kutentha unakhazikitsidwa, kudzatenga mphindi oposa makumi atatu. Pamene ntchito hygrometer ayenera kusamala chifukwa capillaries anapangidwa ndi woonda galasi akhoza kusiya.
The zambiri ntchito psychrometric hygrometer VIT-2. thupi lake unapangidwa pulasitiki. Ndipo ngati madzi mkati capillary ndi toluene. Chinyezi chingwe osiyanasiyana ndi 20 - 90%, ndi kutentha 20 - 40 0 C. hygrometer uyu ali ndi mtengo wotsika, chomasuka muyeso, lonse Kuphunzira chinyezi mfundo - Izo zimatengera kuchuluka kwake. Pakuti chinyezi muyeso pa kutentha m'munsi ntchito hygrometer VIT-1. Timatha kuona osiyanasiyana kutentha pa 5 ndi 25 0 C.
Hygrometer - chida zofunika osati kupanga komanso m'madera zogona komanso chinyezi ayenera kukhala malire wabwinobwino, chifukwa dryness kwambiri za mlengalenga zoipa zokhudza chikhalidwe cha mucous zimagwira ntchito zosiyanasiyana, khungu, ndipo umatithandiza mlingo wa ndalama zimene zingachititse aakulu awo sagwirizana anachita.
