I-Mercury thermometer inomlando weminyaka engaphezu kwengu-300 kusukela ekubukeni kwayo, njengesakhiwo esilula, esisebenza kalula, futhi ngokuyisisekelo izinga lokushisa "lokunemba kwempilo yonke" lapho seliphumile, seliphenduke ithuluzi elikhethwayo lodokotela nokunakekelwa kwezempilo ekhaya ukukala umzimba. izinga lokushisa.

Nakuba ama-thermometer e-mercury eshibhile futhi ewusizo, umhwamuko we-mercury nezinhlanganisela ze-mercury anobuthi kakhulu kuzo zonke izinto eziphilayo, futhi uma esengene emzimbeni womuntu ngokuphefumula, ngokumudla noma ngezinye izindlela, azodala umonakalo omkhulu empilweni yomuntu.Ikakhulukazi ezinganeni, ngoba izitho zabo ezihlukahlukene zisakhula futhi zikhula, lapho ukulimala kwe-mercury poisoning, eminye imiphumela ayinakushintshwa.Ngaphezu kwalokho, inani elikhulu lama-thermometers e-mercury agcinwe ezandleni zethu nawo abe umthombo wokungcola kwemvelo yemvelo, okuyisizathu esibalulekile sokuthi kungani izwe livimbela ukukhiqizwa kwe-mercury equkethe ama-thermometers.

Njengoba ukukhiqizwa kwama-thermometers e-mercury kuvinjelwe, imikhiqizo eyinhloko engasetshenziswa njengezinye izindlela esikhathini esifushane ama-thermometers kagesi kanye nama-thermometers e-infrared.

Nakuba le mikhiqizo inezinzuzo zokuphathekayo, ezisheshayo ukusebenzisa, futhi aziqukethe izinto ezinobuthi, kodwa njengezinto zikagesi, kufanele zisebenzise amabhethri ukuze zinikeze amandla, uma ukuguga kwezingxenye ze-elekthronikhi, noma ibhethri seliphansi kakhulu, lizokwenza imiphumela yokulinganisa ibonakala ukuchezuka okukhulu, ikakhulukazi i-thermometer ye-infrared nayo ithintwa izinga lokushisa langaphandle.Ngaphezu kwalokho, izindleko zakho zombili ziphakeme kancane kunalezo ze-mercury thermometers, kodwa ukunemba kuphansi.Ngenxa yalezi zizathu, akwenzeki ukuthi bashintshe amathemometha e-mercury njengamathemometha anconyiwe ezindlini nasezibhedlela.

Nokho, kuye kwatholakala uhlobo olusha lwe-thermometer - i-gallium indium tin thermometer.I-Gallium indium alloy liquid metal njengento ezwa izinga lokushisa, kanye ne-mercury thermometer, ukusetshenziswa komfaniswano wayo "ukuphakama kokushisa okubandayo okubandayo" izici zomzimba ukukhombisa izinga lokushisa lomzimba elilinganisiwe.Futhi okungezona ubuthi, okungalimazi, uma sekupakishiwe, akukho ukulinganisa okudingekayo empilweni.Njengama-thermometers e-mercury, angabulawa amagciwane ngotshwala futhi asetshenziswe abantu abaningi.

Ngenkinga entekenteke esikhathazeke ngayo, insimbi ewuketshezi ku-thermometer ye-gallium indium tin izoqiniswa ngokushesha ngemuva kokuxhumana nomoya, futhi ngeke iguquguquke ukuze ikhiqize izinto eziyingozi, futhi imfucuza ingelashwa ngokuya ngodoti ojwayelekile wengilazi, futhi ngeke kubangele ukungcoliswa kwemvelo.

Kusukela ngo-1993, inkampani yaseJalimane i-Geratherm yasungula le thermometer futhi yasithumela emazweni angaphezu kuka-60 nasezifundeni emhlabeni jikelele.Kodwa-ke, i-gallium indium alloy liquid thermometer yensimbi yethulwe kuphela e-China eminyakeni yamuva nje, futhi abanye abakhiqizi basekhaya sebeqalile ukukhiqiza lolu hlobo lwe-thermometer.Kodwa-ke, okwamanje, abantu abaningi ezweni abajwayelene kakhulu nale thermometer, ngakho-ke ayidumile kakhulu ezibhedlela nasemindenini.Kodwa-ke, njengoba izwe selikuvimbele ngokuphelele ukukhiqizwa kwe-mercury equkethe ama-thermometers, kukholelwa ukuthi i-gallium indium tin thermometers izothandwa ngokuphelele esikhathini esizayo esiseduze.
