WENKE online pH meter PH/ORP controller

PH-20 PH/ORP controller/PH acidity meter PH-20

Performance characteristics of pH acidity meter PH-20:

1. Factory standard Chinese interface, switchable English interface

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

3. One 4-20mA output, corresponding to PH/ORP value, using isolation technology, 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, convenient for users to operate
