The Model 150 contacting conductivity sensor is a good choice for applications where accuracy over a broad range of conductivity is not necessary. An example is controlling blowdown in open cooling water systems.

The sensor has front and rear-facing 1-inch MNPT process connections. It can be screwed directly into a pipe tee using the front threads or can be attached using the rear threads to a pipe for submersion into a tank or vessel.

The sensor is available with 0.1, 0.5, and 1.0/cm cell constants.
