Online pH meter

Online PH meter A20 typePerformance characteristics:

1. Diverse languages, factory standard Chinese interface, switchable English interface

2. Multiple temperature compensation options including PT1000 NTC10K and manual temperature compensation

3. Two 4-20mA outputs corresponding to PH/ORP values and temperature,Adopting isolation technology, with strong anti-interference ability

4. The high and low points of the two sets of relays can be switched freely, and the hysteresis can be adjusted freely to avoid frequent on-off of the relays

5. Password management function to prevent misoperation by non professionals

6. Menu prompt function greatly facilitates user operation
