Kule mihla, phantse yonke intsapho inayoithemometha yedijithali. Ke, namhlanje siza kuthetha malunga nexesha elidlulileyo nelikhoyo lethemometha.
Ngenye imini ngonyaka we-1592, ingcali yezibalo engumTaliyane Ogama linguGalileo yayinikela intetho kwiYunivesithi yasePadua eVenice, yaye yayisenza ulingelo lokufudumeza imibhobho yamanzi ngoxa yayithetha. Wafumanisa ukuba inqanaba lamanzi kwityhubhu liyenyuka ngenxa yokufudumeza ubushushu, kwaye iqondo lobushushu liyehla xa liphola, Wayecinga ngekomishini evela kumhlobo ugqirha kungekudala: “Xa abantu begula, ubushushu bomzimba wabo. ngokuqhelekileyo iphakama. Ngaba ungayifumana indlela yokulinganisa ubushushu bomzimba ngokuchanekileyo? , ukunceda ekuxilongeni isifo?”
Ekhuthazwe koku, uGalileo wenza ithermometer yetyhubhu yegilasi ngo-1593 ngokusebenzisa umgaqo wokwandiswa kobushushu kunye nokufinyela okubandayo. Kwaye ngo-1612, ngoncedo lwabahlobo abavela kwimimandla eyahlukeneyo, i-thermometer yaphuculwa. Utywala obubomvu bufakwe ngaphakathi, kwaye izikali ze-110 ezikrolwe kwityhubhu yeglasi zingasetyenziselwa ukubona utshintsho lobushushu, olunokusetyenziswa ukulinganisa ubushushu bomzimba.Le yeyona thermometer yokuqala emhlabeni.
Ukususela "kwixesha elidlulileyo" le-thermometer, sinokwazi ukuba i-thermometer ye-mercury yamva nje isebenzisa umgaqo ofanayo wokwandiswa kwe-thermal kunye nokunciphisa okubandayo, kuphela kukuba sithatha indawo yolwelo kwi-thermometer nge-mercury.
Nangona kunjalo, i-mercury yinto eguqukayo kakhulu yentsimbi enzima. Kubikwa ukuba i-thermometer ye-mercury iqulethe malunga ne-1 gram ye-mercury. Emva kokuphulwa, yonke i-mercury evuzayo iyaphuphuma, enokwenza i-mercury igxininise emoyeni kwigumbi elinobukhulu beemitha ezili-15 kunye nokuphakama kweemitha ezi-3 22.2 mg / m3. Abantu abakule meko yoxinaniso lwemekyuri kungekudala baya kubangela ityhefu yemekyuri.
I-Mercury kwi-thermometer yeglasi ye-mercury ayinikeli kuphela umngcipheko ngqo kumzimba womntu, kodwa ibangela umonakalo omkhulu kwindalo.
Ngokomzekelo, ukuba ithermometer yemercury eshiyiweyo yonakalisiwe ize ilahlwe, imercury iya kuguquguquka emoyeni, yaye imekyuri esemoyeni iya kuwela emhlabeni okanye emilanjeni enamanzi emvula, ibangele ungcoliseko. Imifuno ekhuliswe kule mihlaba kunye nentlanzi & Shrimp emilanjeni iya kudliwa sithi kwakhona, ibangela isangqa esibi kakhulu.
Ngokutsho kweSibhengezo seNombolo ye-38 ekhutshwe nguMphathiswa wangaphambili woKhuseleko lweNdalo ngokubambisana nabaphathiswa abafanelekileyo kunye neekhomishini kwi-2017, "iNgqungquthela yaseMinamata yeMercury" yaqala ukusebenza kwilizwe lam ngo-Agasti 16, 2017. yachaza ngokucacileyo ukuba i-mercury thermometers. kwaye iimonitha zoxinzelelo lwegazi zemercury azivumelekanga ukuba zenziwe ukusuka nge-1st/Jan ka-2026.
Ewe kunjalo, ngoku sele sineendlela ezingcono nezikhuselekileyo: ithemometha yedijithali,ithemometha ye-infrared kunye nethemometha yeglasi ye-Indium tin.
Ithemometha yedijithali kunye nethemometha ye-infrared zombini zenziwe ngezava zobushushu, isikrini seLCD, iPCBA, iitshiphusi kunye nezinye izinto zombane. Inokulinganisa ubushushu bomzimba ngokukhawuleza nangokuchanekileyo. Xa kuthelekiswa nethemometha yeglasi yemercury, banezibonelelo zokufunda ngokulula, ukuphendula ngokukhawuleza, ukuchaneka okuphezulu, umsebenzi wememori, kunye ne-alamu ye-beeper. Ngokukodwa i-thermometer yedijithali ayinayo nayiphi na i-mercury. Ingenabungozi kumzimba womntu kunye nendawo engqongileyo, isetyenziswa kakhulu kumakhaya, ezibhedlele kunye nezinye izihlandlo.
Okwangoku, izibhedlele ezininzi kunye neentsapho kwezinye izixeko ezikhulu zithathe indawo yeethemometha zemercury ngethemometha yedijithali kunye nethemometha ye-infrared. Ingakumbi ngexesha le-COVID-19, iithemometha ze-infrared zazingenakubuyiseleka “izixhobo” zokulwa ubhubhane. sikholelwa ukuba ngePropaganda yelizwe, ukuthandwa komntu wonke ngeengozi zemercury, iimveliso zothotho lwemercury ziyakuyekwa kwangethuba.kwaye ithemometha yedijithali iya kusetyenziswa kakhulu kwindawo zonke ezifana nekhaya, isibhedlele kunye nekliniki.
