1. Brief introduction of CM-230 conductivity TDS meter

CM-230 conductivity TDS meter conductivity meter monitor with sensor to test the RO water conductivty whether the product water is qualified. CM-230 conductivity meter with digital monitor is the most easy monitor for water quality test for RO machine.

This instrument is a panel instrument for on-line monitoring of industrial process conductivity. Range switch over and constant check can both be freely set and adjusted through the operation component on the rear panel; unique signal collecting and processing technology and special thick film circuit are adopted to make measurement accurate and operation stable; there are also other features such as realized data, automatic temperature compensation, not subject to the length change of cable and maintenance-free. Its an ideal auxiliary instrument of various types of small pure water equipment.

3. Connection of PLC and recording instrument

The 4-20mA signal is direct output, when the recording instrument or PLC port is connected with the earth of the power supply of the system or floated at a high voltage, the measurement accuracy and safety of electrode will be affected. So the 4-20mA signal isolator is recommended (provided on additional payment).
