Custom-made 3/4 inch MNPT compression fitting for pipe mounting of one pHionics STs Series™ water quality sensor. Unlike compression fittings from other manufacturers, the cmp-k cannot be overtightened so there is no risk of damage to the sensor.

Made from chemical-resistant PVDF. Not suitable for in-line applications involving pressures above 30 psi or temperatures above 30°C.

See below for more information on proper installation of sensors using cmp-k.

Proper Placement of Comparison Fitting

Always place cmp-k close to the cable end.  This allows for accurate temperature measurements and automatic temperature compensation as the temperature sensor is inside the metal housing.
