Resistivity Sensors
All 750II Resistivity models require a CS10 series sensor. This reliable sensor features two integral temperature sensors to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene standard bushing is modular for easy, inexpensive replacement. A PVDF or 316 stainless steel bushing can also be ordered.
The metal portion is available in either 316 stainless steel (standard) or titanium.

Conductivity Sensors
These reliable sensors feature an integral temperature sensor to ensure accurate and rapid automatic temperature compensation. The sturdy polypropylene bushing is modular for easy inexpensive replacement. Several alternatives for the metal portion of the sensor are available, depending on the demands of the application.
CS51LC sensors (0.1 constant) are used for 5 and below.
CS51 sensors (1.0 constant) are used between 0-10 and 0-20,000.
CS52 sensors (10.0 constant) are used above 20,000.
Low cost, low temperature, low pressure sensors available upon request.
See 750II Sensor Selection Guide.
