Humidity indicator cards yog feem ntau txawv los ntawm tus naj npawb ntawm cov ntsiab lus qhia, av noo ntau, xim hloov txoj kev (reversible / irreversible), thiab seb lawv puas muaj cobalt. Lawv tau siv dav hauv kev saib xyuas cov av noo- cov khoom lag luam rhiab heev xws li cov khoom siv hluav taws xob, cov cuab yeej precision, thiab kev ntim tshuaj. Hauv qab no yog cov qauv tseem ceeb ntawm kev faib tawm thiab cov neeg sawv cev ntawm lub khw:
Kev faib tawm los ntawm Tus lej ntawm Cov Ntsiab Lus Qhia
Peb -Point Humidity Indicator Card
Cov av noo ib puag ncig: 5% / 10% / 60%, 30% / 40% / 50%, 5% / 10% / 15% Haum rau cov xwm txheej uas xav tau tshwj xeeb rau cov av noo tseem ceeb, xws li cov ntim khoom semiconductor (J-STD-033 tus qauv pom zoo siv 5% / 10% / 60%)
Piv txwv qauv: 51060HIC125 (Cobalt-dawb, xim av rau daj, ua raws li IPC/JEDEC J-STD-033D txuj)
Plaub -Point Humidity Indicator Card
Common humidity gradients: 10% / 20% / 30% / 40% los yog 20% / 30% / 40% / 50% Muab cov av noo zoo saib xyuas ntau yam, haum rau kev ntim khoom nrog cov kev xav tau nruab nrab.
Rau -point humidity indicator card
Cov av noo gradients: 10% / 20% / 30% / 40% / 50% / 60% Kev dav dav, yooj yim los txiav txim cov av noo hloov pauv, feem ntau siv hauv SMT tivthaiv ntim. Xim hloov logic: Xiav thaum tsis nqus dej noo, hloov xim liab tom qab nqus dej; thaum qhov txheeb ze av noo nyob nruab nrab ntawm cov xim -hloov thiab tsis yog-xim- hloov cov ntsiab lus, tus nqi tiag tiag tuaj yeem txiav txim los ntawm lub teeb liab doog hauv nruab nrab.
Tib - point humidity indicator card
Saib xyuas cov av noo tshwj xeeb (xws li 30% RH lossis 60% RH). Tus nqi qis, tsim nyog rau cov xwm txheej yooj yim uas tsuas yog qhov kev txwv yuav tsum tau txiav txim siab.
