Mercury thermometer ine nhoroondo yemakore anopfuura 300 kubva pakuonekwa kwayo, sechimiro chakareruka, chiri nyore kushanda, uye chaizvoizvo "yehupenyu hwese" thermometer kana yangobuda, yave ndiyo inoshandiswa kune vanachiremba uye hutano hwehutano hwepamba kuyera muviri. tembiricha.

Kunyange zvazvo mercury thermometers isingadhuri uye inoshanda, mercury vapor uye mercury makomisheni ane muchetura kuzvinhu zvese zvipenyu, uye kana angopinda mumuviri wemunhu kuburikidza nekufema, kupinza kana imwe nzira, anokonzeresa kukuvadza kukuru kuhutano hwevanhu.Kunyanya kuvana, nokuti nhengo dzavo dzakasiyana-siyana dzichiri mukukura nekukura, kana kukuvadza kwe mercury chepfu, mimwe migumisiro haigoneki.Pamusoro pezvo, nhamba huru yemercury thermometers inochengetwa mumaoko edu yavewo chitubu chekusvibiswa kwezvakatipoteredza, chiri chikonzero chakakosha nei nyika ichirambidza kugadzirwa kwemekiyuri ine mathermometers.

Sezvo kugadzirwa kwemercury thermometers kwakarambidzwa, zvigadzirwa zvikuru zvinogona kushandiswa sedzimwe nzira munguva pfupi ndeyemagetsi thermometers uye infrared thermometers.

Kunyangwe zvigadzirwa izvi zvine zvakanakira zvinotakurika, zvinokurumidza kushandisa, uye zvisina zvinhu zvine chepfu, asi semidziyo yemagetsi, zvinofanirwa kushandisa mabhatiri kupa simba, kana kuchembera kwezvinhu zvemagetsi, kana bhatiri rakaderera, rinoita kuyerwa mhedzisiro inoratidzika kutsauka kukuru, kunyanya iyo infrared thermometer inobatwawo nekunze tembiricha.Zvakare, mutengo wezvose zviri zviviri wakakwira zvishoma pane iyo yemercury thermometers, asi iko kurongeka kwakadzikira.Nekuda kwezvikonzero izvi, hazvigoneke kuti vatsive ma mercury thermometers seyakakurudzirwa mathermometer mudzimba nemuzvipatara.

Zvisinei, rudzi rutsva rwethermometer rwakawanwa - gallium indium tin thermometer.Gallium indium alloy liquid simbi sechinhu chinonzwa tembiricha, uye mercury thermometer, kushandiswa kweyunifomu yayo "inotonhora inotonhora kupisa kusimuka" maitiro emuviri kuratidza kuyerwa kwekushisa kwemuviri.Uye isiri-chepfu, isingakuvadze, kana yaiswa mukati, hapana calibration inodiwa kwehupenyu.Sezvinoita mercury thermometers, anogona kuuraya utachiona nedoro uye kushandiswa nevanhu vakawanda.

Nekuda kwedambudziko risina kusimba ratiri kunetsekana naro, simbi yemvura mugallium indium tin thermometer inosimbiswa pakarepo mushure mekusangana nemhepo, uye haizonyunguduke kuburitsa zvinhu zvinokuvadza, uye tsvina inogona kurapwa zvinoenderana nemarara egirazi. uye hazvizokonzeri kusvibiswa kwezvakatipoteredza.

Kubva muna 1993, kambani yekuGermany yeGeratherm yakagadzira thermometer iyi uye yakatengesa kunze kwenyika dzinopfuura makumi matanhatu nematunhu pasi rose.Nekudaro, gallium indium alloy liquid metal thermometer yakangounzwa kuChina mumakore achangopfuura, uye vamwe vagadziri vemumba vatanga kugadzira rudzi urwu rwethermometer.Zvakadaro, pari zvino, vanhu vazhinji munyika havanyatso ziva nezvethermometer iyi, saka haina kufarirwa zvakanyanya muzvipatara nemhuri.Zvisinei, sezvo nyika yakarambidza zvachose kugadzirwa kwemercury ine thermometers, zvinotendwa kuti gallium indium tin thermometers ichave yakakurumbira zvachose munguva pfupi iri kutevera.
