The WPA1 retractable holders provide a compact and convenient way of installing the industry standard 12 x 120 mm PG13.5 ProcessProbe into a process line or tank. It is important that pH sensors are calibrated and serviced regularly, the WPA1 allows the operator to safely remove the sensor without interrupting the process. Only when the housing is fully retracted and the process sealed can the rear cover be removed allowing access to the pH sensor.
The WPA1 is available in two materials CPVC for general purpose use, the PEEK version provides extended chemical resistance and a higher temperature/pressure specification.
