Technical Parameter

FEATURES
Easy to install:Simple structure, easy installation, firm and reliable.
Insulation impedance:Under normal conditions, when the instrument is in a closed circuit state, the insulation impedance between the power supply lead and the casing should be measured using the impedance meter specified by the state and should be above 20M Ω.
Insulation strength:The power supply line of the instrument can withstand 50Hz, 1500V, with a current limit of 5mA, for a duration of 1 minute without any arcing or breakdown.
Mean time between failures and continuous operation:Using actual water samples, the instrument runs continuously for 2 months, recording the total running time (h) and the number of failures (times), and calculating the mean time between failures (MTBF) ≥ 720h/time.
