Intelligent: This industrial PH meter adopts high-precision AD conversion and single chip microcomputer processing technologies and can be used for the measurement

of the PH values and temperature, automatic temperature compensation and self checking.

Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting knob or potentiometer is arranged on this instrument.

Double high impedance input: The latest components are adopted; The impedance of the double high impedance input can reach as high as l0¹²Ω. It has strong interference immunity.

Solution grounding: This can eliminate all the disturbance of the ground circuit.

Isolated current output: Optoelectronic isolating technology is adopted. This meter has strong interference immunity and the capacity of long-distance transmission. 

Communication interface: it can be easily connected to a computer to perform monitoring and communication.

Automatic temperature compensation: It performs automatic temperature compensation when the temperature is within the range of 0~99.9°C. Its protection 

grade is IP54.

Display, menu and notepad: It adopts menu operation, which is like that in a computer. It can be easily operated only according to the prompts and without  guidance of the

operation manual.

Multi-parameter display: The PH values, input mV values (or output current values), temperature, time and status . It is applicable for outdoor use.
