Ho lekanya thermometer ke mokhoa oa ho etsa sekala holim'a thermometer. Mona ke mehato e meng ea ho e etsa. ho lekanya thermometer. Ppele, lokisa thermometer ea mercury kapa thermometer ea joala ntle le sekala. KKe ne ke rata., lokisa leqhoa le lekaneng. Ktse tharo, lokisa metsi a lekaneng. Ea bone, Lokisetsa 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 tletseng 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 o sebelisa hitara ea motlakase kapa setofo J. Kenya thermometer ka setshelong se nang le metsi a futhumatsoang. Ha metsi a chesa kapa suhu Ha boemo ba metsi bo ntse bo nyoloha, bolelele ba kholomo ea mercury le bona boa eketseha (bokaholimo ba mercury bo nyolohela holimo). Hang ha metsi a bela, karolo e ka holimo ea kholomo ea mercury e khaotsa ho sisinyeha. Tšoaea pheletso ea kholomo ea mercury. Ena ke ntlha ea ho belisa ea metsi, kapa ntlha ea mouoane oa eona.
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.
Thempereichara ea 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 lipalo tse fapaneng. Li-thermometer tsa mercury tse sebelisoang hangata li lekanngoa sepakapakeng se le seng, kahoo ntlha ea ho hoama ea metsi ke 0. oC 'me mocheso oa ntlha ea ho belisa ke 100 oC.
Li-thermometer tse tloaelehileng, tse kang li-thermometer tsa mercury kapa alcohol, hangata li na le bokhoni bo fokolang. Li ke ke tsa sebelisoa ho lekanya mocheso o tlase haholo (ka tlase ho 0°C).oC) kapa mocheso o phahameng haholo (o fetang 100)oC).
