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
1.Smart sensor, iyo tembiricha 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.
2.Low tembiricha drift, muhuwandu hwe5 ~ 50 ℃, kuyera kwemagetsi kuyerwa kuri nani pane 0.01, uye kugadzirisa ndeye 0.001 ℃, iyo inogona kusangana neyakajairwa tembiricha calibration zvinodiwa.
3.In U disk mode, kuchaja kana kutumira data kunogona kuitwa kuburikidza neMicro USB interface, iyo iri nyore kukurumidza kugadzirisa yedata data.
4.Gravity sensing function, inotsigira automatic screen flipping, uye yakanakira kuverenga ruzivo inogona kuwanikwa nokuiisa kuruboshwe kana kurudyi.
5.Support Bluetooth kana ZigBee kutaurirana, unogona kushandisa Panran Smart Measurement APP kuwiriranisa data kana kuwedzera mamwe maapplication.
6.Protection class IP64 yekushandisa yakavimbika munzvimbo dzakaoma.
7.Ultra-yakaderera simba rekushandisa, yakavakirwa-mukati rechargeable lithium bhatiri, basa rinoenderera mberi kwemaawa anopfuura 130.
Mamwe Mabasa
1. Volatility kuyerwa panguva yakatarwa nguva
2.Relative tembiricha kuyerwa
3. Maximum, shoma uye avhareji kukosha kuverenga
4. Electrical value / tembiricha kukosha kutendeuka
5. Sensor kururamisa kukosha kugadzirisa
6. Pamusoro pekushisa kwearamu
7. Yakavakwa-in high precision chaiyo nguva wachi
8. Sarudzo ℃, ℉, K
