Pathfinders is an Authorized Value-Added Reseller of Sensorex Products

Sensorex has been the preeminent supplier of products to measure and monitor water quality for over 40 years now.  We offer their full range of standard sensors and possess the capabilities to design and manufacture all their water quality sensors to help meet even the most demanding customer’s needs.

Here at Pathfinders Instruments, we manufacture transmitters and can customize controllers that we package together with the Sensorex probes to give you turnkey systems for your OEM water quality needs.  We offer everything from Conductivity to Resistivity, pH, ORP and DO.

Sensorex boiler conductivity sensors use 3/4" male NPT threads. Both the body and the measuring pin are constructed of 316 stainless steel. They feature a special thermally resistant PEEK insert and high temperature "O" rings. Two models are available, and each model may be ordered with or without ATC elements depending upon your application requirements.  Models CS675, CS676, and CS650 are designed for general use conductivity measurements. 

The new CS8000TC sensor is an easy-to-install conductivity sensor, ideally suited for cooling TDS monitoring.  A keyed flange is used to align the sensor in the ideal orientation for trouble free monitoring.  Sensor removal is simple with the detachable S855 cable assembly.  There's no need to pull the cable through conduit -- just hand-loosen the knurled nut and remove the sensor.   We at Pathfinder Instruments are proud to join the Sensorex family and look forward to a long and fruitful partnership.
