Anti corrosion PTFE pH meter

Large screen dot matrix LCD display, Chinese menu operation, simultaneous display of multiple parameters: PH/ORP value

Temperature, output current, alarm points, etc. are displayed simultaneously, which is intuitive and easy to read.

Automatic temperature compensation function.

Communication function: Equipped with RS-485 communication interface (partially compatible with MODBUS protocol) (optional),

Capable of converting to RS-232. The PH/ORP value corresponding to the 4-20 mA current output can be set.
