Conductivity Meter

This industrial online conductivity meter is a microprocessor-based water quality monitoring instrument. It can be used with different types and constants of conductivity electrodes to continuously monitor and control the conductivity and temperature of aqueous solutions with high measurement accuracy. Equipped with two sets of relay control switches, it features standard 4-20mA output and RS485 communication output, making it suitable for power plant cooling water, seawater desalination, and various water treatment equipment, providing accurate monitoring and control of raw water and treated water quality.
