The Model 567 All Plastic Hot Tap Retractable Sensor. If your piping is corrosion resistant plastic, shouldn’t your pH sensor be the same? The Model 567 is specifically designed for use in the most aggressive measurement applications. It is the only “All Plastic” hot tap retractable pH sensor available to the market. The 567 sensor uses a Kynar insertion body thus eliminating the metallic sheath typically used with cartridge style hot tap sensors. Not only can it withstand strong chemicals; the Kynar body provides a great solution in applications that build-up and adhere to metallic parts.

Insertion Depth
The depth that pH / ORP sensor protrudes into the pipeline can greatly affect the measurement. Applications where the sensor tip is recessed can lead to coating and slow response. In high particulate applications abrasion of the electrode can be a concern.
A typical installation goal is to get the sensor tip at least 1/4" (6mm) into the stream. At this depth coating issues lessen and response improves due to flow velocity.
