RM-220 type resistivity meterDetailed product description：

RM-220 resistivity monitoring instrument

1、 Performance characteristics:

This instrument is a resistivity monitoring device that displays both resistivity and temperature simultaneously, and has an online panel type instrument with low resistivity alarm function. It is widely used in industries such as pharmaceuticals, electronics, and chemical engineering for online monitoring of industrial process water quality. It adopts microcontroller technology to freely set the temperature coefficient, electrode constant, and low limit alarm point of pure water through the buttons on the panel, making it an ideal matching instrument for various small and medium-sized pure water equipment.
