Spirax Sarco CP30

Conductivity probe

Spirax Sarco CP30 is a conductivity sensor designed to measure the total conductivity (TDS) of water in steam boilers and other vessels. It is used in conjunction with a blowdown controller to monitor boiler water quality and automatically control blowdown, ensuring safe and efficient boiler operation.

The sensor is installed directly into the boiler (via a flange, sensor elbow, or threaded connection) and is available in several lengths that can be cut to size for specific installations.

All water-contacting parts are made of stainless steel and PTFE, ensuring resistance to high temperatures and the aggressive environment of boiler water.
