PR721 / PR722 Series Precision Digital Thermometer
PR721 series precision digital tus pas ntsuas kub txais cov khoom siv ntse nrog cov qauv ntsuas phoo, uas tuaj yeem hloov pauv nrog cov ntsuas ntsuas sib txawv kom tau raws li qhov ntsuas kub sib txawv.Cov kev txhawb nqa sensor hom muaj xws li hlau-qhov txhab platinum tsis kam, nyias-film platinum tsis kam, thermocouple thiab av noo sensors, uas tuaj yeem txheeb xyuas thiab thauj cov hom, qhov kub thiab txias thiab kho tus nqi ntawm kev sib txuas sensor.Tus pas ntsuas kub yog ua los ntawm txhuas alloy tag nrho, nrog IP64 tiv thaiv chav kawm, uas tuaj yeem siv tau kev ntseeg siab hauv qhov chaw hnyav.
Technical nta
1. Ntse sensor, qhov kub thiab txias npog -200 ~ 1300 ℃.Siv cov khoom ntsuas kub-tiv thaiv kev ntsuas kub, tus tswv tsev tuaj yeem tuaj yeem thauj khoom tam sim no sensor hom, qhov ntsuas kub thiab kho tus nqi tom qab txuas mus rau lub ntse sensor, txhim kho qhov tseeb ntawm qhov kub thiab txias traceability, thiab kev ua haujlwm zoo.
2. Tsis tshua muaj kub drift, nyob rau hauv thaj tsam ntawm 5 ~ 50 ℃, qhov ntsuas hluav taws xob raug zoo dua li 0.01, thiab qhov kev daws teeb meem yog 0.001 ℃, uas tuaj yeem ua tau raws li cov qauv ntsuas kub siab.
3. Nyob rau hauv U disk hom, them los yog cov ntaub ntawv kis tau tus mob yuav ua tau los ntawm Micro USB interface, uas yog yooj yim rau kev kho kom ceev cov ntaub ntawv xeem.
4. Lub ntiajteb txawj nqus sensing muaj nuj nqi, txhawb tsis siv neeg tshuaj ntsuam flipping, thiab zoo tagnrho kev nyeem ntawv yuav muab tau los ntawm muab tso rau sab laug los yog txoj cai.
5. Txhawb Bluetooth lossis ZigBee kev sib txuas lus, koj tuaj yeem siv Panran Smart Measurement APP los synchronize cov ntaub ntawv lossis nthuav tawm lwm daim ntawv thov.
6. Kev tiv thaiv chav kawm IP64 rau kev siv tau zoo hauv qhov chaw hnyav
7. Ultra-tsawg zog noj, built-in rechargeable lithium roj teeb, ua hauj lwm tas mus li ntau tshaj 130 teev.
