He mōʻaukala ʻo Mercury thermometer i ʻoi aku ma mua o 300 mau makahiki mai kona ʻike ʻia ʻana, ma ke ʻano he ʻano maʻalahi, maʻalahi e hana, a ʻo ke ʻano "lifelong precision" ka thermometer i ka wā i puka mai ai, ua lilo ia i mea pono no nā kauka a me ka mālama ola home e ana i ke kino. mahana wela.

ʻOiai he mea maʻalahi a maʻalahi nā thermometers mercury, he mea ʻawaʻawa loa ka uahu mercury a me nā pūhui mercury i nā mea ola a pau, a ke komo lākou i ke kino o ke kanaka ma o ka hanu ʻana, ʻai ʻana a i ʻole nā ​​mea ʻē aʻe, e hōʻeha nui lākou i ke olakino kanaka.ʻOi loa no nā keiki, no ka mea, aia nō kā lākou mau ʻano like ʻole i ke kaʻina o ka ulu ʻana a me ka hoʻomohala ʻana, i ka wā i hōʻeha ʻia ai ka make ʻana o ka mercury, hiki ʻole ke hoʻololi ʻia kekahi mau hopena.Eia kekahi, ʻo ka nui o nā thermometers mercury i mālama ʻia i loko o ko mākou mau lima ua lilo i kumu o ka haumia kūlohelohe kūlohelohe, ʻo ia ke kumu nui e pāpā ai ka ʻāina i ka hana ʻana i nā thermometer me ka mercury.

Ma muli o ka pāpā ʻia ʻana o ka hana ʻana o nā thermometers mercury, ʻo nā huahana nui e hiki ke hoʻohana ʻia e like me nā mea ʻokoʻa i ka wā pōkole ʻo ia nā thermometer uila a me nā thermometer infrared.

ʻOiai ua loaʻa i kēia mau huahana nā mea maikaʻi o ka lawe lima, wikiwiki e hoʻohana, a ʻaʻole i loko o nā mea ʻawaʻawa, akā ma ke ʻano he mea uila, pono lākou e hoʻohana i nā pihi e hāʻawi i ka ikehu, i ka wā o ka ʻelemakule o nā mea uila, a i ʻole ka haʻahaʻa o ka pākaukau, e hana i ka ʻIke ʻia nā hopena ana i ka ʻokoʻa nui, ʻoi aku ka hopena o ka thermometer infrared e ka wela o waho.ʻO ka mea hou aku, ʻoi aku ka kiʻekiʻe o ke kumukūʻai o nā mea ʻelua ma mua o nā thermometer mercury, akā ʻoi aku ka haʻahaʻa o ka pololei.Ma muli o kēia mau kumu, ʻaʻole hiki iā lākou ke hoʻololi i nā thermometer mercury e like me nā thermometer i ʻōlelo ʻia ma nā hale a me nā halemai.

Eia naʻe, ua ʻike ʻia kahi ʻano ana wela hou - gallium indium tin thermometer.ʻO Gallium indium alloy wai metala ma ke ʻano he mea ʻike wela, a me ka thermometer mercury, ʻo ka hoʻohana ʻana i kāna ʻano ʻano like ʻole "ka piʻi ʻana o ka wela i ke anuanu" e hōʻike i ke ana wela o ke kino.A ʻaʻohe mea ʻawaʻawa, ʻaʻohe pōʻino, hoʻokahi pūʻulu, ʻaʻohe pono calibration no ke ola.E like me nā thermometer mercury, hiki ke hoʻopau ʻia me ka waiʻona a hoʻohana ʻia e nā poʻe he nui.

No ka pilikia palupalu a mākou e hopohopo nei, e hoʻopaʻa ʻia ka metala wai i loko o ka thermometer gallium indium tin ma hope koke o ka hoʻopili ʻana me ka ea, a ʻaʻole e hoʻoheheʻe ʻia e hana i nā mea ʻino, a hiki ke mālama ʻia ka ʻōpala e like me ka ʻōpala aniani maʻamau. a ʻaʻole e hoʻohaumia i ke kaiapuni.

I ka makahiki 1993, ua hana ka hui Kelemania ʻo Geratherm i kēia thermometer a lawe aku iā ia i nā ʻāina ʻoi aku ma mua o 60 a me nā wahi a puni ka honua.Eia naʻe, ua hoʻolauna ʻia ka gallium indium alloy liquid metala i Kina i nā makahiki i hala iho nei, a ua hoʻomaka kekahi mau mea hana hale e hana i kēia ʻano ana wela.Eia nō naʻe, i kēia manawa, ʻaʻole maopopo loa ka hapa nui o ka ʻāina i kēia thermometer, no laila ʻaʻole kaulana loa i nā halemai a me nā ʻohana.Eia naʻe, ʻoiai ua pāpā loa ka ʻāina i ka hana ʻana i ka mercury i loko o nā thermometers, ua manaʻo ʻia e kaulana loa nā thermometers gallium indium tin i ka wā e hiki mai ana.
