Ho lekanya thermometer ke mokhoa oa ho etsa sekala holim'a thermometer. Mehato e meng ea ho lekanya thermometer ke ena . Ea pele , lokisa thermometer ea mercury kapa thermometer ea joala ntle le sekala. Ea bobeli , lokisa leqhoa le lekaneng. Ea boraro , lokisa metsi a lekaneng. Ea bone , lokisa hitara ea metsi e ka sebelisoang ho futhumatsa metsi ho fihlela a bela. Ea bohlano , kenya leqhoa le metsi ka setshelong (metsi le leqhoa li na le boima bo lekanang). Kamora moo, kenya thermometer ka setshelong se nang le metsi le leqhoa.
Qalong, thermometer e kopana le moea, e leng se etsang hore e chese ho feta leqhoa. Kamora ho beoa ka setshelong, bolelele ba kholomo ea mercury bo tla fokotseha hobane motsoako oa metsi le leqhoa o bata haholo. Lumella bolelele ba kholomo ea mercury hore bo lule bo sa fetohe (karolo e ka holimo ea mercury ha e sisinyehe). Ha bolelele ba kholomo ea mercury bo lula bo sa fetohe, motsoako oa li-cubes tsa leqhoa le metsi o fihlile mochesong oa oona o phahameng ka ho fetisisa. tekatekano ea mochesoTšoaea sebaka sa kholomo ea mercury (tšoaea karolo e ka holimo ea kholomo ea mercury). Ena ke mocheso oa ntlha ea leqhoa kapa ntlha ea ho hoama ea metsi.
Ea botšelela , belisa metsi u sebelisa hitara ea motlakase kapa setofo J. Kenya thermometer ka setshelong se nang le metsi a futhumatsoang. Ha metsi a ntse a chesa kapa mocheso oa metsi o ntse o eketseha, bolelele ba kholomo ea mercury le bona boa eketseha (bokaholimo ba mercury bo ea holimo). Kamora hore metsi a bele, bokaholimo ba mercury bo khaotsa ho sisinyeha. Tšoaea pheletso ea kholomo ea mercury. Ena ke mocheso oa ntlha ea ho belisa ea metsi kapa ntlha ea mouoane.
Haeba o batla ho theha sekala sa Celsius, sebaka se pakeng tsa matshwao a mabedi se arotswe ka mela e 100, moo sebaka se pakeng tsa mola ka mong se lokelang ho tshwana. Letshwao le ka tlase = 0o C, ha letšoao le ka holimo = 100o C. Sheba setšoantšo ka lehlakoreng.
Mocheso oa ntlha ea ho hoama le ntlha ea mouoane li itšetlehile ka khatello ea moea. Ka hona, li-thermometer tse lekanngoang ka khatello e fapaneng ea moea li tla fana ka liphetho tse fapaneng. Li-thermometer tsa mercury tse sebelisoang hangata li lekanngoa moeeng o le mong, kahoo ntlha ea ho hoama ea metsi ke 0 ° C 'me ntlha ea ho belisa ke 100 ° C.
Hangata li-thermometer tse tloaelehileng, tse kang li-thermometer tsa mercury kapa alcohol, lia fokola. Li ke ke tsa sebelisoa ho lekanya mocheso o tlase haholo (ka tlase ho 0 ° C) kapa mocheso o phahameng haholo (ka holimo ho 100 ° C).
