W8287 Ammonia Nitrogen Saib Xyuas

Cov yam ntxwv ntawm cov cuab yeej:

● LCD kua siv lead ua zaub

● Kev ua haujlwm ntawm cov ntawv qhia zaub mov ntse

● Ntau yam kev ua haujlwm calibration tsis siv neeg

● Hom ntsuas teeb liab sib txawv, ruaj khov thiab txhim khu kev qha

● Kev them nyiaj kub ntawm tes thiab tsis siv neeg

● Ob pawg ntawm cov relay tswj switches

● Kev tswj tus nqi siab, qis, thiab hysteresis

● Nws qhia txog qhov concentration ntawm ion, kub, tam sim no, thiab lwm yam ntawm lub interface.

● Nws kuj muaj kev tiv thaiv lo lus zais kom tiv thaiv cov neeg ua haujlwm tsis raug cai los ntawm kev ua yuam kev.
