PR721/PR722 Series Precision Digital Thermometer
PR721 yakatevedzana chaiyo dhijitari thermometer inotora yakangwara sensor ine kukiya chimiro, iyo inogona kutsiviwa nemasensor eakasiyana maratidziro kuti asangane neakasiyana tembiricha zvinodiwa.Mhando dze sensor dzinotsigirwa dzinosanganisira waya-ronda platinamu kuramba, yakaonda-firimu platinamu kuramba, thermocouple uye humidity sensors, iyo inogona kungoziva uye kurodha mhando, tembiricha yemhando uye kukosha kwekugadziriswa kweiyo yakabatana sensor.Iyo thermometer yakagadzirwa nealuminium alloy yakazara, ine IP64 kirasi yekudzivirira, inogona kushandiswa zvakavimbika munzvimbo dzakaoma.
Technical Features
- Smart sensor, tembiricha yemhando inovhara -200 ~ 1300 ℃.Uchishandisa yakakwira tembiricha inodzivirira kukiya zvikamu, muenzi anogona kurodha yazvino sensor mhando, tembiricha yemhando uye kukosha kwekugadziriswa mushure mekubatanidza kune yakangwara sensor, kuvandudza iko kurongeka kwekushisa kuteedzera, uye kushanda nesimba.
- Kuderera kwekushisa kwekushisa, muhupamhi hwe5 ~ 50 ℃, kuyera kwemagetsi kuri nani pane 0.01, uye kugadzirisa ndeye 0.001 ℃, iyo inogona kusangana nepamusoro-soro yekuenzanisa kwekushisa zvinodiwa.
- MuU disk modhi, kuchaja kana kutumira data kunogona kuitwa kuburikidza neMicro USB interface, iyo iri nyore kukurumidza kugadzirisa yebvunzo data.
- Gravity inonzwa basa, inotsigira otomatiki chidzitiro kubhururuka, uye yakanaka kuverenga ruzivo inogona kuwanikwa nekuiisa kuruboshwe kana kurudyi.
- Tsigira Bluetooth kana ZigBee kutaurirana, unogona kushandisa Panran Smart Measurement APP kuwiriranisa data kana kuwedzera mamwe maapplication.
- Dziviriro kirasi IP64 yekushandisa yakavimbika munzvimbo dzakaoma.
- Ultra-yakaderera simba rekushandisa, yakavakirwa-mukati rechargeable lithium bhatiri, inoenderera ichishanda kweanopfuura maawa zana nemakumi matatu.
