Namuhla, cishe yonke imindeni inawoi-thermometer yedijithali.Ngakho-ke, namuhla sizokhuluma mayelana nesikhathi esedlule nesamanje se-thermometer.
Ngolunye usuku ngonyaka ka-1592, isazi sezibalo esingumNtaliyane okuthiwa uGalileo sasinikeza inkulumo eNyuvesi yasePadua eVenice, futhi sasenza ucwaningo lokushisisa amapayipi amanzi ngenkathi sikhuluma.Uthole ukuthi izinga lamanzi epayipini liyakhuphuka ngenxa yokushisa kwezinga lokushisa, futhi izinga lokushisa liyehla lapho liphola, Wayecabanga ngekhomishini evela kumngane kadokotela esikhathini esingeside esidlule: “Lapho abantu begula, izinga lokushisa lomzimba wabo. ngokuvamile liyakhuphuka.Ungakwazi yini ukuthola indlela yokulinganisa izinga lokushisa lomzimba ngokunembile?, ukusiza ekuxilongeni isifo?”
Ekhuthazwa yilokhu, uGalileo wasungula i-bubble glass tube thermometer ngo-1593 ngokusebenzisa isimiso sokunwetshwa kokushisa nokufinyela okubandayo.Futhi ngo-1612, ngosizo lwabangane abavela emikhakheni ehlukene, izinga lokushisa lathuthukiswa.Utshwala obubomvu obunamabala afakwa ngaphakathi, futhi izikali ezingu-110 eziqoshwe eshubhuni lengilazi zingasetshenziswa ukubona ukushintsha kwezinga lokushisa, elingasetshenziswa ukukala izinga lokushisa lomzimba.Lesi yi-thermometer yokuqala emhlabeni.
Kusukela "esikhathini esidlule" se-thermometer, singakwazi ukuthi i-thermometer yakamuva ye-mercury isebenzisa isimiso esifanayo sokunwetshwa kokushisa kanye nokunciphisa okubandayo, okuwukuphela kokuthi sishintsha uketshezi ku-thermometer nge-mercury.
Kodwa-ke, i-mercury iyinsimbi enamandla kakhulu eguquguqukayo.Kubikwa ukuthi i-thermometer ye-mercury iqukethe cishe igremu elingu-1 le-mercury.Ngemva kokuphulwa, yonke i-mercury evuzayo iyahwamuka, engenza ukugxila kwe-mercury emoyeni ekamelweni elinobukhulu obungamamitha-skwele angu-15 nobude obungamamitha angu-3 22.2 mg/m3.Abantu abakule ndawo yokuhlushwa kwe-mercury ngokushesha bazobangela ubuthi be-mercury.
I-Mercury ku-thermometer yengilazi ye-mercury ayinikezi nje ingozi eqondile emzimbeni womuntu, kodwa futhi idala umonakalo omkhulu emvelweni.
Ngokwesibonelo, uma i-mercury thermometer eshiywe ilahliwe yonakaliswa futhi ilahlwa, i-mercury izoshintshashintsha emoyeni, futhi i-mercury emkhathini iyowela emhlabathini noma emifuleni ngamanzi emvula, ibangele ukungcola.Imifino etshalwa kule nhlabathi kanye nezinhlanzi & Shrimp emifuleni izophinde idliwe yithi, okubangela umbuthano omubi kakhulu.
Ngokusho kweSimemezelo No. 38 esikhishwe uMnyango Wezokuvikelwa Kwemvelo wangaphambili ngokubambisana nezinkonzo ezifanele kanye namakhomishana ngo-2017, "I-Minamata Convention on Mercury" yaqala ukusebenza ezweni lami ngo-August 16, 2017. isho ngokucacile ukuthi i-Mercury thermometers futhi iziqapha ze-mercury blood pressure zinqatshelwe ukuthi zenziwe kusukela ngomhlaka-1/Jan ka-2026.”
Yebo, Manje sesivele sinezinye izindlela ezingcono neziphephile: ithemometha yedijithali,ithemometha ye-infrared kanye ne-Indium tin glass thermometer.
Ithemometha yedijithali ne-infrared thermometer zombili zakhiwe ngezinzwa lokushisa, isikrini se-LCD, i-PCBA, ama-chips nezinye izinto zikagesi.Ingakwazi ukukala izinga lokushisa lomzimba ngokushesha nangokunembile.Uma ziqhathaniswa ne-thermometer yengilazi ye-mercury evamile, zinezinzuzo zokufunda okulula, ukuphendula okusheshayo, ukunemba okuphezulu, umsebenzi wenkumbulo, ne-alamu ye-beeper.Ikakhulukazi i-thermometer yedijithali ayinayo i-mercury.Ayinangozi emzimbeni womuntu nendawo ezungezile, isetshenziswa kabanzi emakhaya, ezibhedlela nakwezinye izikhathi.
Njengamanje, izibhedlela eziningi kanye nemindeni kwamanye amadolobha amakhulu ithathe indawo yamathemometha e-mercury yafaka i-digital thermometer kanye ne-infrared thermometer.Ikakhulukazi ngesikhathi se-COVID-19, ama-thermometer e-infrared “ayeyizikhali” zokulwa nobhubhane ezingenakususwa.sikholelwa ukuthi ngePropaganda yezwe, ukuthandwa kwawo wonke umuntu ngezingozi zemercury, imikhiqizo yochungechunge lwemercury izoyekwa kusenesikhathi.futhi i-thermometer yedijithali izosetshenziswa kabanzi kuzo zonke izindawo njengasekhaya, isibhedlela kanye nomtholampilo.
