Ama-thermometer amadivayisi avumela ukuthi silinganise izinga lokushisa kwento, umuntu, isilwane, okokusebenza, ukudla, imvelo ... Nganoma yiluphi uhlobo lwesilinganiso okufanele sisenze, sinohlobo oluhlukile lwe-thermometer. Ngaphakathi kwama-thermometer, singathola futhi amafomethi ahlukile: ikakhulukazi i-analog ne-digital.
Uma kukhulunywa ngokulinganisa izinga lokushisa lokudla lapho sikupheka, esivivinyweni selabhorethri noma kunoma yisiphi esinye isimo lapho kudingeka khona ukwazi izinga lokushisa ngokunembile, asikwazi ukusebenzisa ama-thermometer wendabuko, kepha siyaphoqeleka sebenzisa ama-thermometer elabhorethri.
Yini i-thermometer yaselebhu
Njengoba ngishilo esigabeni esedlule, ama-thermometer elebhu, okuyi ikakhulukazi zidijithali kusivumela ukukala izinga lokushisa ngokunembile, ngoba le yingxenye efanelekile, ikakhulukazi lapho kunesidingo sokuyigcina ukuze sifeze iphrojekthi esiyenzayo.
Lolu hlobo lwe-thermometer lusinikeza isikali sokulinganisa lokho ingahluka ngomkhiqizi nangemodeli, ngakho-ke kufanele sikunake lapho sifuna ithemometha laselabhorethri elihlangabezana nezidingo zethu, ezikhona nezesikhathi esizayo uma sifuna ukunweba ukusetshenziswa kwalo kumaphrojekthi azayo.
Anjani ama-thermometer elebhu
Ama-thermometer elebhu, yize igama lawo lingakhombisa ukuthi yizinto ezikhethekile, Akukho okunye okuqhubekayo kusuka eqinisweni. Lezi zinhlobo zama-thermometer zisinikeza ukwakheka okufanayo esingakuthola kuma-thermometer wendabuko we-mercury / gallium uma sikhuluma ngama-thermometer we-analog.
Ama-thermometer we-Analog afana nawo ingilazi ende ende enebhalbhu ekugcineni ikuphi into ezosivumela ukuthi silinganise izinga lokushisa futhi elizoshintsha ukwakheka kuye ngokushisa kwento esiyikalayo.
Yize iningi lama-thermometer elebhu esingalithola eYurophu usinikeza ukulinganisa ngama-degree CelsiusEzinye zifaka nezikali zeFahrenheit neKelvin.
Ama-thermometer edijithali, ngokungafani nalawo asetshenziselwa ukukala izinga lokushisa komzimba, anosayizi ohlangene kakhulu, omile njengesikwele futhi okumele xhuma inzwa yokukala. Lawa ma-thermometer afaka isikrini lapho izinga lokushisa likhonjiswa esikalini esasisungule ngaphambili: i-Celsius, iFahrenheit noma i-Kelvin.
Izingxenye ze-thermometer yaselebhu
Ama-thermometers e-laboratory e-analog akhiwe ngeshubhu yengilazi lapho izilinganiso ezinikezwayo zikhonjiswa khona. Ngaphakathi, siyathola i-capillary lapho uketshezi olusetshenziselwe ukulinganisa khona luzungeza khona (gallium / galinstan noma utshwala obunemibala). Ekugcineni, sithola isibani, ingxenye engezansi ye-thermometer lapho uketshezi olusetshenziselwa ukukala lutholakala khona.
Ama-thermometer edijithali, njengoba igama lawo libonisa, yimishini kagesi leyo kufaka phakathi iphenyo engahluka ngobude lapho sithola khona inzwa yokwenza izilinganiso. Le nzwa ithumela isignali kagesi ophikweni oluphakathi, oluzophatha ukuluhumusha ukuze lunikeze imininingwane esiyifunayo.
Ngokungafani nama-thermometer we-analog, ama-thermometer edijithali inikwa amandla ibhethri, ibhethri okumele lihlale lisesimweni esihle uma singafuni ukwenza izilinganiso eziyiphutha ezingonakalisa i-laboratory yethu, iphrojekthi yokupheka ...
Ukunemba kwama-thermometer elebhu
Uma ufuna ama-thermometers aselabhorethri anembe kakhulu, kakhulu kungakuhle ukhethe i-thermometer yedijithali, yize ngenxa yezindleko zayo eziphakeme, kungenzeka ukuthi iphume emaphaketheni ethu, inqobo nje uma sicubungula imodeli yekhwalithi enezitifiketi eziqinisekisa ukusebenza okufanele nezilinganiso ezinembile.
Lolu hlobo lwama-thermometer zihlale zishesha kakhuluKodwa-ke, azeluleki lapho kufanele senze isilinganiso entweni eshisa kakhulu noma ebanda kakhulu, ikakhulukazi uma ikhebula lokulinganisa lifushane kakhulu.
Kulezi zimo, inketho engcono ukukhetha i-thermometer yelabhorethri yengilazi, ama-thermometer ezimeni eziningi, idlule u-30 cm ubude ngakho-ke sigwema ubungozi bokuletha isandla sisondele kakhulu entweni esifuna ukuyikala.
Linganisa i-thermometer yaselebhu
Njengoba ngishilo esigabeni esedlule, ama-thermometer elabhorethri, womabili edijithali ne-analog, anemba kakhulu, inqobo nje uma enziwe yizinkampani eqinisekisiwe phambilini yiNational Accreditation Entity (ENAC).
Akufani ukuthola isilinganiso sokushisa esingalungile esivivinyweni sasekhaya kunesilinganiso esingalungile esivivinyweni, ngoba uma singalungile, iphrojekthi yonke ingonakala futhi kufanele ngiqale ekuqaleni.
Lapho uthenga i-thermometer yelabhorethri, kufanele sicabangele izitifiketi zomkhiqizi, uma sifuna ukuthi izilinganiso zithembeke ngokoqobo ngobuncane bephutha, umkhawulo wephutha kunasesimweni selaboratori yokulinga, kufanele bika ngemiphumela.
I-thermometer ngayinye yaselebhu kumele faka amamajini wephutha avumelekile, amamajini wephutha asukela ku-0,5º C, aze afike ku-2º C ngaphezu kuka-1º C. Lawa ma-margins wephutha kufanele afakwe emiphumeleni yesilingo.
Uma sizohlala sisebenzisa i-thermometer ukwenza izilinganiso ngaphansi kwezimo ezijwayelekile, akudingekile ukulinganisa njalo njalo. Uma kunalokho, kufakwa emazingeni okushisa angafanele isikhathi eside, kufanele sicabangele ukulinganisa i-thermometer kanye ngonyaka.
Ungalinganisa kanjani i-thermometer
Kunezindlela ezimbili zokulinganisa ama-thermometer: ngokuqhathanisa nangamaphuzu amisiwe.
Ukulinganisa ngokuqhathanisa kuqukethe ukuqhathanisa ukufundwa kwe-thermometer okuzolinganiswa nokufundwa kwe-thermometer okuyizimpawu ezaziwayo. Le ndlela yokulinganisa isuselwa kuMthetho kaZeroth. Umthetho kaZeroth uthi uma izinhlelo ezimbili zisezingeni lokulingana, ngayinye yazo inezinga lokushisa elifanayo nohlelo lwesithathu, lezi zinhlelo zombili zinamazinga okushisa afanayo.
Ukulinganiswa kwephoyinti elungisiwe. Ukulinganiswa kwamaphoyinti angaguquki kwenziwa kusetshenziswa amaphoyinti okushisa angaguquki, njengamanzi eqhwa, ngoba iqhwa liyancibilika ku-0ºC futhi limiswe lapho kushisa khona.
