Use the economical Sludge Watch 715 portable sludge blanket detector to spot check sludge interface levels in settling tanks. It works by measuring the change in the level of suspended solids as the IP68-rated PVC sensor is lowered into a tank.

When the sensor reaches the sludge blanket, an audible signal changes from a fast beeping to a slow beeping tone and a red LED provides a visual indication. Rugged sensor cable markings (in one-foot intervals from the sensor) allow you to measure the sludge interface position.

The sludge detector consists of a cable reel and an IR sensor. The cable reel contains all electronics and a replaceable 9V battery, and stores the 33-ft sensor cable when not in use.
