1. 16 bit high accuracy AD and low power microprocessor technology.
2. Multi-level password protection, reliable and safe measurement data.
3. Automatically identify and calibrate the PH standard solution. Automatic temperature compensation
4. High resolution graphic LCD which can display the PH (mV) value, temperature, date, electrode slope, zero position, output current, etc. simultaneously.
5. Two analog (pH/mV and temperature) isolated output and digital signal output ( RS485 / standard MODBUS protocol) can be chosen.
6. 4-way alarm relay and 1-way cleaning control relay output
7. Isolated power supply is adopted to measure and output. Strong anti-interference ability.
