PR721/PR722 Series Precision Digital Thermometer
PR721 series precision digital thermometer siv lub sensor ntse nrog lub qauv xauv, uas tuaj yeem hloov nrog cov sensors ntawm ntau yam kev qhia kom tau raws li qhov xav tau ntsuas kub sib txawv. Cov hom sensor txhawb nqa suav nrog hlau-qhov txhab platinum tsis kam, nyias-zaj duab xis platinum tsis kam, thermocouple thiab av noo sensors, uas tuaj yeem txheeb xyuas thiab thauj cov hom, qhov kub thiab txias thiab tus nqi kho ntawm lub sensor txuas nrog. Lub ntsuas kub yog ua los ntawm txhuas alloy tag nrho, nrog IP64 tiv thaiv chav kawm, uas tuaj yeem siv tau zoo hauv cov chaw ib puag ncig hnyav.
Cov Nta Txuj Ci
1. Lub sensor ntse, qhov kub thiab txias npog -200 ~ 1300 ℃. Siv cov khoom xauv uas tiv taus kub siab, tus tswv tsev tuaj yeem thauj cov hom sensor tam sim no, qhov kub thiab txias thiab tus nqi kho tom qab txuas rau lub sensor ntse, txhim kho qhov tseeb ntawm kev taug qab kub, thiab kev ua haujlwm zoo.
2. Qhov kub qis qis, nyob rau hauv qhov ntau ntawm 5 ~ 50 ℃, qhov tseeb ntawm kev ntsuas hluav taws xob zoo dua 0.01, thiab qhov kev daws teeb meem yog 0.001 ℃, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua kom kub siab.
3. Hauv hom U disk, kev them lossis xa cov ntaub ntawv tuaj yeem ua tiav los ntawm Micro USB interface, uas yooj yim rau kev kho cov ntaub ntawv sim sai.
4. Muaj nuj nqi ntsuas lub ntiajteb txawj nqus, txhawb nqa qhov screen tig tsis siv neeg, thiab kev nyeem ntawv zoo tagnrho tuaj yeem tau txais los ntawm kev tso nws sab laug lossis sab xis.
5. Txhawb Bluetooth lossis ZigBee kev sib txuas lus, koj tuaj yeem siv Panran Smart Measurement APP los synchronize cov ntaub ntawv lossis nthuav lwm yam kev siv.
6. Kev tiv thaiv chav kawm IP64 rau kev siv tau zoo hauv cov chaw ib puag ncig hnyav
7. Siv hluav taws xob tsawg heev, roj teeb lithium uas ua tau dua tshiab, ua haujlwm tas mus li ntau dua 130 teev.
