2. Ua tib zoo saib xyuas cov pab pawg tshwj xeeb
Thermometers tuaj yeem ntsuas lub cev kub rau peb, tab sis rau qee pawg tshwj xeeb, kev yuav khoom ntawm cov ntsuas kub yuav tsum tau ceev faj ntau dua. Piv txwv li, thaum cov poj niam cev xeeb tub xaiv lub ntsuas kub basal, nws raug nquahu kom xaiv lub ntsuas hluav taws xob hluav taws xob, uas muaj kev nyab xeeb dua vim nws tsis muaj mercury. Tau kawg, koj tsis tuaj yeem yuav tus ntsuas dej zoo tib yam, koj yuav tsum yuav tus poj niam tshwj xeeb tus pas ntsuas kub, uas muaj qhov tseeb dua thiab ntsuas qhov tseeb dua. Thaum yuav khoom, nws yuav tsum raug sau tseg tias qhov tseeb yuav tsum yog ±0.05 degree kom haum rau cov poj niam kom ntsuas qhov ntsuas kub ntawm lub cev.
3. Yuav raws li xav tau
Yog tias cov neeg siv khoom xav siv cov ntsuas kub digital lossis pob ntseg rau kev ntsuas lub cev kub, lawv yuav tsum tau saib xyuas qee cov ntsiab lus. Ua ntej tshaj plaws, vim yog qhov yuav tsum tau ua nruj me ntsis rau kev ntsuas kub ntawm lub cev, qhov qhia qhov yuam kev ntawm tus pas ntsuas kub feem ntau yuav tsum yog ±0.1 degree, thiab qhov tseeb ntawm qhov ntsuas kub ntawm cov neeg siv khoom yuav tsum ua raws li qhov yuav tsum tau ua; thib ob, ua tib zoo nyeem cov lus qhia thiab ua tib zoo mloog cov ntsiab lus tseem ceeb ntawm kev ua haujlwm.
