InPro 7108-VP/CPVC Conductivity Sensor

New product
More info

For industrial wastewater.

The 4-electrode sensor InPro  7108-VP/CPVC is used in medium/high conductivity applications ranging from drinking water to industrial wastewater and has been specially designed and ruggedly built to withstand the harshest process conditions. The 1" thread allows direct installation in pipes and the compact design allows easy installation, even in small pipes. The sensor can be installed together with the immersion housing InDip 550 or with the flow-through housing InFlow 751.

WideRange technology makes the sensor suitable for a variety of applications ranging from drinking water up to industrial waste water. The flat surface of the sensor reduces significantly fouling and makes maintenance simple. The watertight (IP68) VarioPin connector ensures excellent signal transmission even under extremely humid conditions and direct water contact.

Features and Benefits


Wide measuring range while maintaining a compact sensor design. This allows cost-saving installation and standardization in many applications. 

Increased reliability

The IP68 rated VarioPin connector system ensures excellent and hassle-free signal transmission and stops problems associated with humidity. It also saves money compared to fixed cable installations. 

Flat surface

The design of the sensor prevents from significant fouling and increases the reliability of the sensor. Especially in wastewater utilities, low maintenance requirement is a key factor.
