Mowa thermometer ndi botolo la galasi ndi capillary yomwe ili ndi mowa kapena zakumwa zina zofiira. Choncho, ngati kuchuluka kwa kutentha kwa pamsewu, madzi akumwa mu thermometer, ndipo pamene amachepetsanso, amavomereza.
Bimetallic street thermometer, kukumbutseni kwa ola ndi muvi, sikulondola mozama kuposa mowa, koma chifukwa cha muvi waukulu ukuwonekeratu kutali. Zochita za thermometerzi zimachokera ku malo a zida zamadzimadzi (zosanjikiza ziwiri zazitsulo) kusintha ndi kubwezeretsanso mawonekedwewa chifukwa cha kutentha.
Msewu wa thermometers pamsewu
Kachipangizo kamakono kanyumba kamene kali ndi thermometer ndi kujambula kwa digito LCD, yomwe ikhoza kukhala kunja kapena kuphatikizidwa.
