Thermometers michina inotibvumidza kuyera tembiricha yechinhu, munhu, mhuka, zvinhu, chikafu, nharaunda ... Kune chero rudzi rweyero yatinofanira kuita, isu tine imwe mhando ye thermometer. Mukati meiyo thermometer, isu tinogona zvakare kuwana mafomati akasiyana: kunyanya analog uye dijitari
Kana zvasvika pakuyera tembiricha yechikafu patiri kuchibika, muyedzo murabhoritari kana mune chero imwe mamiriro ezvinhu panofanirwa kuziva kutonhora chaizvo, hatigone kushandisa echinyakare mahemometha, asi isu tinomanikidzwa shandisa ma laboratory thermometer.
Chii chinonzi laboratory thermometer
Sezvandamboreva mundima yapfuura, mahemoromathometri erabhoritari, ayo ivo vanonyanya kuve digital inotibvumidza kuyera tembiricha nenzira kwayo, nekuti ichi chikamu chakakosha kwazvo, kunyanya pazvinenge zvakakodzera kuchichengetedza kuitira kuti tiite chirongwa chatiri kuita.
Rudzi urwu rwe thermometer runotipa chiyero chekuyera icho inogona kusiyana nemugadziri uye modhi, saka isu tinofanirwa kuzvifunga kana tichitsvaga thermometer yeLaboratory inosangana nezvatinoda, zviripo uye nezveramangwana kana tichida kuwedzera mashandisiro ayo kumapurojekiti emangwana.
Akadii marabhoritari thermometers
Ma laboratori thermometer, kunyangwe zita ravo rinogona kuratidza kuti zvinhu zvakakosha, Hapana chimwezve chinobva pane chaicho. Aya marudzi eezve thermometer anotipa iwo akafanana dhizaini atinogona kuwana mune echinyakare mercury / gallium thermometer kana tikataura nezveanalog thermometer.
Analog thermometers akaumbwa senge refu girazi chubhu ine girobhu racho kumucheto chiripiko chinhu chinotibvumidza kuyera tembiricha uye icho chinozochinja chimiro zvichienderana netembiricha yechinhu chatiri kuyera.
Kunyangwe mazhinji emarabhoromathomitha erabhoritari atinogona kuwana muEurope inotipa chiyero mumadhigirii CelsiusZvimwe zvinobatanidza zviyero zveFahrenheit neKelvin.
Dhijitari thermometer, kusiyana neaya anoshandiswa kuyera tembiricha yemuviri, ane akaenzana akaenzana saizi, muchimiro chekwere uye kwatinofanira batanidza chiyero cheyero. Aya ma thermometer anosanganisira skrini uko tembiricha inoratidzwa pachiyero chatakatangisa kare: Celsius, Fahrenheit kana Kelvin.
Zvikamu zveyemeter thermometer
Analog laboratory thermometer inoumbwa negirazi chubhu uko zviyero zvaunopa zvinoratidzwa. Mukati, tinowana capillary iyo iyo mvura inoshandiswa kuita kuyerwa inotenderera (gallium / galinstan kana kara doro). Chekupedzisira, tinowana girobhu racho, chikamu chepazasi cheye thermometer panowanikwa mvura inoshandiswa kuyera.
Dhijitari thermometer, sekuratidzwa kwezita ravo, zvigadzirwa zvemagetsi izvo inosanganisira probe inogona kusiyanisa pakureba kwatinowana iyo sensor yekuita zviyero. Iyi sensor inotumira chiratidzo chemagetsi kuchikamu chepakati, icho chichava mutariri wekuchidudzira kuti chipe data ratiri kutsvaga.
Kusiyana neanalog thermometers, edhijitari thermometer dzinofambiswa nebhatiri, bhatiri rinofanirwa kugara riri muchimiro chakanaka kana tisingade kuita zviyero zvisina kunaka zvinogona kukanganisa yedu yatove marabhoritari, chirongwa chekugadzirira ...
Kururama kwema laboratory thermometers
Kana iwe uchitsvaga chaiyo chaiyo marabhoritari thermometers, zvakanyanya zvinokurudzirwa kusarudza digital thermometerKunyangwe zvichikonzerwa nemutengo wayo wakakwira, zvinogona kubuda muhomwe medu, chero bedzi isu tiri kufunga yemhando yemhando nezvitupa izvo zvinoona kushanda kwakakodzera uye zviyero chaizvo.
Rudzi urwu rwema thermometer vanogara vachikurumidzaNekudaro, izvo hazvikurudzirwe kana tichifanira kuita kuyerwa kuchinhu chinopisa kana chinotonhora zvakanyanya, kunyanya kana tambo yekuyera ipfupi zvakanyanya.
Muzviitiko izvi, yakanakisa sarudzo kusarudza yegirazi re laboratori thermometer, mahemometha ayo mune mazhinji mamiriro, inopfuura 30 cm kureba saka tinodzivirira njodzi yekuunza ruoko padhuze nechinhu chatinoda kuyera.
Chengetedza iyo thermometer yerabhoritari
Sezvandambotaura muchikamu chakapfuura, ma thermometer erabhoritari, ese ari maviri edhijitari neanalogog, akarurama chaizvo, sekureba sekunge akagadzirwa nemakambani anga yakambopupurirwa neNational Accreditation Entity (ENAC).
Hazvina kufanana kuti uwane kuyerwa kwakashata kwetembiricha muyedzo yemumba pane kuyerwa kusiri iko mukuyedza, nekuti kana zvisiri, chirongwa chese chinogona kuenda kunoparara uye kutanga kubva pakutanga.
Kana tichitenga thermometer yerabhoritari, isu tinofanirwa kufunga nezvezvigadzirwa zvemugadziri, kana tichida kuti zviyero zvive zvakatendeka kuchokwadi nemugumo wepasi wekukanganisa, muganho wekukanganisa kupfuura mune rabhoritari rekuyedza. taura nezve mhedzisiro.
Yese ye laboratori thermometer inofanirwa inosanganisira margins anotenderwa ekukanganisa, margins ekukanganisa anotangira pa0,5ºC, anosvika pa2º C kuwedzera pa1º C. Iyi micheto yekukanganisa inofanirwa kuverengerwa mumhedzisiro yekuyedza.
Kana iyo thermometer iri kugara ichizoshandiswa kuita zviyero pasi pechinyakare mamiriro, hazvidiwe kuti uzvibatanidze nguva zhinji. Kana, kune rimwe divi, ichiiswa pasi pekupisa kwakasarongeka kwenguva yakareba, isu tinofanirwa kufunga nezve kudzikamisa iyo thermometer kamwe pagore.
Maitiro ekuyera thermometer
Pane nzira mbiri dzekuenzanisa mahemometha: nekuenzanisa uye nepfungwa dzakatarwa.
Kuenzanisa nekuenzanisa inosanganisira kuenzanisa kuverenga kwethermometer kuti ienzaniswe nekuverengwa kwethermometer ine hunhu hunozivikanwa. Iyi nzira yekugadzirisa inoenderana neMutemo waZeroth. Mutemo weZeroth unoti kana masisitimu maviri ari muchimiro chekufananidza, imwe neimwe iine tembiricha yakafanana neyechitatu system, iwo masisitimu maviri ane tembiricha yakafanana seimwe.
Yakagadziriswa poindi calibration. Yakagadziriswa poindi calibration inoitwa uchishandisa yakatarwa tembiricha mapoinzi, senge mvura yechando, nekuti chando chinonyungudika pa0ºC uye inotonhora pane imwechete tembiricha.
