I-thermometer ye-Mercury inembali engaphezulu kweminyaka engama-300 ukususela ekubonakaleni kwayo, njengesakhiwo esilula, kulula ukuyisebenzisa, kwaye ngokusisiseko i-thermometer "echanekileyo ubomi bonke" xa iphuma, ibe sisixhobo esikhethwayo koogqirha kunye nokunakekelwa kwezempilo ekhaya ukulinganisa ukushisa komzimba.

Nangona i-mercury thermometers zixabiso eliphantsi kwaye zisebenza, umphunga wemercury kunye neekhompawundi zemercury zinetyhefu kakhulu kuzo zonke izinto eziphilayo, kwaye nje ukuba zingene emzimbeni womntu ngokuphefumla, ukuginya okanye ezinye iindlela, ziya kubangela ingozi enkulu kwimpilo yabantu. Ngokukodwa kubantwana, ngenxa yokuba amalungu abo ahlukeneyo asekho kwinkqubo yokukhula kunye nophuhliso, emva kokulimala kwe-mercury poisoning, ezinye iziphumo zingenakuguqulwa. Ukongeza, inani elikhulu le-mercury thermometers ezigcinwe ezandleni zethu ziye zaba ngumthombo wokungcola kwendalo, okusisizathu esibalulekileyo sokuba ilizwe livimbela ukuveliswa kwe-mercury equkethe i-thermometers.

Ekubeni ukuveliswa kwee-thermometers ze-mercury kuvaliwe, iimveliso eziphambili ezinokuthi zisetyenziswe njengezinye iindlela kwixesha elifutshane ziyi-thermometers ze-elektroniki kunye ne-infrared thermometers.

Nangona ezi mveliso zineenzuzo eziphathwayo, ezikhawulezayo ukusebenzisa, kwaye aziqulathanga izinto ezinetyhefu, kodwa njengezixhobo zombane, kufuneka zisebenzise iibhetri ukunika amandla, xa ukuguga kwamacandelo e-elektroniki, okanye ibhetri iphantsi kakhulu, iya kwenza ukuba iziphumo zomlinganiselo zibonakale zitenxa enkulu, ngakumbi ithemometha ye-infrared nayo ichatshazelwa bubushushu bangaphandle. Ngaphezu koko, iindleko zazo zombini ziphezulu kancinci kunezo zethemometha zemercury, kodwa ukuchaneka kuphantsi. Ngenxa yezi zizathu, akunakwenzeka ukuba bathathe indawo yeethemometha zemercury njengeethemometha ezicetyiswayo ezindlini nasezibhedlele.

Nangona kunjalo, uhlobo olutsha lwe-thermometer lufunyenwe - i-gallium indium tin thermometer. I-Gallium indium alloy liquid metal njengesixhobo sokubona ubushushu, kunye ne-mercury thermometer, ukusetyenziswa kweyunifomu yayo "i-cold contraction heat rise" iimpawu zomzimba ukubonisa ubushushu bomzimba obulinganisiweyo. Kwaye ayinayo ityhefu, engeyongozi, xa sele ipakishwe, akukho lungelelwaniso lufunekayo ebomini. Njengakwithemometha zemercury, zinokubulawa iintsholongwane ngotywala kwaye zisetyenziswe ngabantu abaninzi.

Kuba ingxaki eethe-ethe ukuba sikhathazeke ngayo, ulwelo lwesinyithi kwi-gallium indium tin ithemometha iya kuqiniswa ngoko nangoko emva kokudibana nomoya, kwaye akayi volatilize ukuvelisa izinto eziyingozi, kwaye inkunkuma inokunyangwa ngokwenkunkuma yeglasi eqhelekileyo, kwaye ayiyi kubangela ungcoliseko lokusingqongileyo.

Kwangowe-1993, inkampani yaseJamani iGeratherm yavelisa le themometha kwaye yathumela kumazwe angaphezu kwama-60 nakwimimandla yehlabathi. Nangona kunjalo, i-gallium indium alloy liquid thermometer yensimbi iye yaziswa kuphela e-China kwiminyaka yamuva nje, kwaye abanye abavelisi basekhaya baye baqala ukuvelisa olu hlobo lwe-thermometer. Nangona kunjalo, okwangoku, abaninzi abantu belizwe abaqhelananga kakhulu nale thermometer, ngoko ayithandwa kakhulu kwizibhedlele nakwiintsapho. Nangona kunjalo, ekubeni ilizwe liye lavala ngokupheleleyo ukuveliswa kwe-mercury equkethe i-thermometers, kukholelwa ukuba i-gallium indium tin thermometers iya kuthandwa ngokupheleleyo kwixesha elizayo.
