FAQ
Q: Dab tsi yog qhov tseem ceeb ntawm cov av sensor?
A: Nws tuaj yeem saib xyuas peb txheej ntawm av noo noo Kub EC Salinity NPK cov ntsiab lus ntawm qhov sib txawv ntawm tib lub sijhawm.Nws muaj kev tiv thaiv corrosion, muaj zog rigidity, siab raug, ceev teb, thiab tuaj yeem muab faus rau hauv av.
Q: Kuv puas tuaj yeem tau txais cov qauv?
A: Yog, peb muaj cov ntaub ntawv hauv Tshuag los pab koj kom tau txais cov qauv sai li sai tau.
Q: Dab tsi yog cov khoom siv hluav taws xob thiab cov teeb liab tso tawm?
A: 5 ~ 30V DC thiab peb muaj qhov sib tw hnub ci zog.
Q: Kuv tuaj yeem sau cov ntaub ntawv li cas?
A: Koj tuaj yeem siv koj tus kheej cov ntaub ntawv logger lossis wireless kis tau tus mob module yog tias koj muaj, peb muab RS485-Mudbus kev sib txuas lus raws tu qauv.
Q: Tus qauv cable ntev yog dab tsi?
A: Nws tus qauv ntev yog 1m.Tab sis nws tuaj yeem hloov kho, MAX tuaj yeem yog 1200 meters.
Q: Lub neej ntawm no Sensor yog dab tsi?
A: Tsawg kawg yog 3 xyoos lossis ntau dua.
Q: Kuv puas tuaj yeem paub koj qhov warranty?
A: Yog, feem ntau nws yog 1 xyoos.
Q: Lub sijhawm khoom xa tuaj yog dab tsi?
A: Feem ntau, cov khoom yuav raug xa hauv 1-3 hnub ua haujlwm tom qab tau txais koj cov nyiaj them poob haujlwm.Tab sis nws nyob ntawm koj qhov ntau.
Q: Dab tsi yog lwm daim ntawv thov scenario tuaj yeem siv ntxiv rau kev ua liaj ua teb?
A: Roj pipeline tsheb thauj mus los saib xyuas, cov pa roj carbon monoxide xa mus saib xyuas kev thauj mus los, kev saib xyuas kev tiv thaiv corrosion
