PR721/PR722 Series Precision Digital Thermometer
PR721 mndandanda mwatsatanetsatane digito thermometer utenga kachipangizo wanzeru ndi dongosolo lokhoma, amene akhoza m'malo ndi masensa specifications zosiyanasiyana kukwaniritsa zosowa zosiyanasiyana kutentha muyeso.Mitundu yothandizidwa ndi sensa imaphatikizapo kukana kwa platinamu ya waya, kukana kwa platinamu yopyapyala, thermocouple ndi sensa ya chinyezi, yomwe imatha kuzindikira ndikunyamula mtunduwo, kutentha kwamtundu ndi mtengo wowongolera wa sensor yolumikizidwa.Thermometer imapangidwa ndi aloyi ya aluminiyamu yonse, yokhala ndi gulu lachitetezo la IP64, lomwe lingagwiritsidwe ntchito modalirika m'malo ovuta.
Zaukadaulo
1. Sensa yanzeru, kutentha kwamtundu kumakwirira -200 ~ 1300 ℃.Pogwiritsa ntchito zida zotsekera zosagwira kutentha kwambiri, wolandirayo amatha kunyamula mtundu wa sensor yomwe ilipo, kuchuluka kwa kutentha ndi mtengo wowongolera pambuyo polumikizana ndi sensor yanzeru, kuwongolera kulondola kwa kutentha, komanso kugwira ntchito moyenera.
2. Kutsika kwa kutentha kwapansi, pamtunda wa 5 ~ 50 ℃, kulondola kwa magetsi kuli bwino kuposa 0.01, ndipo chisankho ndi 0.001 ℃, chomwe chingathe kukwaniritsa zofunikira za kutentha kwapamwamba.
3. Mu disk U disk mode, kulipiritsa kapena kutumiza deta kungathe kuchitidwa kudzera mu mawonekedwe a Micro USB, omwe ndi osavuta kusintha mwamsanga deta yoyesera.
4. Ntchito yozindikira mphamvu yokoka, imathandizira kutembenuzika kwa zenera, komanso kuwerenga koyenera kungapezeke poyiyika kumanzere kapena kumanja.
5. Thandizani Bluetooth kapena kulankhulana kwa ZigBee, mungagwiritse ntchito Panran Smart Measurement APP kugwirizanitsa deta kapena kukulitsa ntchito zina.
6. Gulu lachitetezo IP64 kuti ligwiritsidwe ntchito modalirika m'malo ovuta
7. Kugwiritsa ntchito mphamvu zotsika kwambiri, kumangidwanso mu batri ya lithiamu, ntchito yosalekeza kwa maola oposa 130.
