CM-508 type dual channel conductivity monitoring instrumentDetailed product description：

CM-508 conductivity meter

1、 Performance characteristics:

The CM-508 conductivity meter is an online measurement and control instrument for industrial process water quality, which integrates conductivity and temperature measurement. It can simultaneously sample and measure two channels, and the conductivity values of the two channels can be switched and displayed through buttons. It adopts microcontroller technology, and the temperature coefficient, electrode constant, and conductivity upper limit alarm points of pure water can be freely set through buttons. Widely used in industries such as pharmaceuticals, electronics, and chemicals for online monitoring of pure water. It is an ideal matching instrument for various small and medium-sized pure water equipment.

2、 Main features of CM-508 dual channel conductivity monitor
