CM-230KA conductivity meter

CM-230KA conductivity meter

Overview

The CM-230KA conductivity meter is an upgraded product of our company's CM-230 conductivity monitoring instrument. On the basis of maintaining the original product performance, it uses a microcontroller digital circuit for measurement and temperature compensation. This product is widely used for online conductivity measurement and monitoring of water treatment equipment such as reverse osmosis, seawater desalination, and electrodialysis. It has the characteristics of more convenient use, easier operation, and more complete performance.
