Digital Conductivity Meter/ Controller Introduction

Digital conductivity meter/controller has functions of automatic temperature compensation, automatic alarm for upper and lower limits, isolated analog signal output 4-20mA, RS485 remote communication, power-down memory, etc. Conductivity meter adopts anti-static metal paint, sealed waterproof back cover and sealed waterproof joints can improve anti-interference ability, anti-corrosion ability and stability. Online conductivity meter and matched 4 conductivity electrodes have measuring range from 0.02μS/cm~0.02mS/cm to 0.02mS/cm~20mS/cm, can be used for online conductivity monitoring of different liquids such as pure water, tap water, sewage, and concentrated liquid.

Digital Conductivity Meter/ Controller Feature


● Conductivity (TDS) and temperature measurement, upper limit control, current output and digital communication.
● It can be free to adjust the conductivity temperature compensation coefficient and TDS conversion coefficient.
● Two relays, conductivity (TDS) and temperature can be controlled respectively, and the hysteresis can be adjusted freely.
● In a set of instrument mode isolation transmission port can be configured with electrical conductivity (TDS) or temperature, the maximum loop resistance of 300 Ω.
● Voice alarm switch function, through the interface options setting on or off.
● LCD backlight can choose energy-saving mode, auto off timer.
● High performance CPU, excellent electromagnetic compatibility.
● One click restore factory parameter function.
● Password management functions, prevent misuse of non professional personnel.

Digital Conductivity Meter/ Controller Application

  1. Conductivity measurement of RO membrane equipment: Digital conductivity meter is suitable for monitoring the conductivity of liquids such as pure water and raw water during the processing of various RO (Reverse Osmosis) membrane equipments.

  2. Conductivity measurement of water and fertilizer: Online conductivity meter can measure the conductivity value of the solution and feed back the signal to the PLC to achieve the precise ratio of water and fertilizer and effectively reduce waste.

  3. Process measurement of conductivity: Monitor the change of liquid conductivity during ultrasonic cleaning, circulating water in air conditioning, and electroplating production, and can set upper and lower limits to achieve automatically alarm.

  4. Environmental water quality monitoring: It is suitable for on-line monitoring of liquid conductivity of tap water, seawater and sewage exhaust outlets, and data can be transmitted with MODBUS via RS485.
