Cov cua kub cua tshuab ziab khaub ncaws

Kev ua haujlwm zoo rwb thaiv tsev – JB / t5520-91 tus qauv tau teev tseg tias rau cov desiccant nrog lub siab ua haujlwm kub tsis tshaj 200 ℃.Peb lub tuam txhab txais cov ntaub ntawv zoo tshwj xeeb thiab tshwj xeeb rwb thaiv tsev tshuab.

Qhov kub thiab txias uniformity-JB / T5520-91 tus qauv qhia tias “qhov ntsuas kub tsis sib xws ntawm lub tshuab hluav taws xob ziab kom qhuav tsis ntau dua ± 2.5% ntawm qhov kub siab tshaj” (rau qhov cub tua hluav taws kub, nws yog ± 2.5% × 200 ℃ = ± 5 ℃). Cov txheej txheem tsim khoom thiab cov txheej txheem kev tso kawm thaum ziab ua kom zoo dua qhov sib piv ntawm cov cua ntim thiab cov qauv ntawm cov kav dej, thiab txhim kho qhov kub thiab txias nyob rau hauv qhov cub kom nyob rau hauv qhov ntau ntawm ± 3 ° C;
