CM-230D conductivity meter

CM-230D conductivity meter

Overview

The CM-230D 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 seawater desalination, and can meet the electrostatic interference and electrode chuck connection requirements of stainless steel equipment. It has the characteristics of more convenient use, easier operation, and more complete performance.
