Thin water quality measurement module

Surveillance; High precision measurement; Proofreading support; DC power supply; DIN rail mounting; No water quality information provided; Analog output.

This is a slim electrical resistivity (resistivity) measurement module.
It features analog output (4-20mA) and allows for dual output of water quality and water temperature.
Its slim and compact design contributes to space saving in control panels and other applications. This
electrical resistivity (resistivity) measurement module is ideal for measuring pure and ultrapure water used in semiconductor and pharmaceutical applications.
Please use it in combination with the 7701 sensor series.
