Water quality measurement module

Surveillance; High concentration measurement possible

This is an electrical conductivity (electrical conductivity) measurement module.
It features analog output (4-20mA) and can output two parameters: water quality and water temperature.
Its slim and compact design allows for space-saving installation in control panels and other locations.
It can measure high concentrations up to 10,000 μS/cm.
It can be used for applications such as wastewater and liquid fertilizer management.
