Features

 Intelligent: This Industrial Conductivity meter adopts high precision AD conversion and single chip microcomputer  processing technologies and can be used for the measurement of the conductivity values and temperature, automatic 

temperature compensation and self-checking.

High Reliability: All the components are arranged on one circuit board. No complicated functional switch, adjusting 

knob or potentiometer arranged on this instrument.

Strong interference immunity: Its current output adopts optoelectronic isolating technology. This meter has strong 

interference immunity and the capacity of long-distance transmission as well as excellent electromagnetic compatibility.

Water proof and dust-proof design: Its protection grade is IP65. It is applicable for outdoor use. 

25℃ Conversion: The conductivity value measured at the current temperature is converted to that at 25;thus, this 

conductivity meter always displays the conductivity value at 25. Therefore, this meter is especially suitable for testing the 

various water solutions in power plants.

Automatic range switching: The measuring ranges can automatically switch within the measuring range of the electrode.

Communication interface: RS485, It can be easily connected to a computer to perform monitoring and communication

Phase sensitive detection: Eliminating the influence of conductors on the measurement of conductivity.
