605 – SS Ball Valve Retractable pH Sensor

The model 605 meets the requirement for a ball valve insertion sensor in pulp & paper stock lines and other difficult applications.

The small cross-section steel housing with epoxy-encapsulated sensor better survives the rigors of direct insertion into dense stock. Larger-diameter sensors are more subject to pressures that can cause breakage during insertion and removal caused by bending of the sensor.

This sensor was originally requested as a replaceable cartridge style. However, cartridges experienced drifting and premature failure due to moisture reaching the BNC fitting on the back of the sensor cartridge. The Model 605 single-piece epoxy-encapsulated sensor eliminates the moisture problem and provides long, trouble-free operating life.
