Keeping Your Sensors Clean

Your sensors should be cleaned regularly, depending on bather load and characteristics specific to your facility. It's a relatively easy process. First, turn off your controller and all feeders. Close flow cell valves. Remove the sensors from the flow cell by unscrewing by hand and disconnect connectors. Carefully place your sensors into a clean container with water to ensure the tip remains wet.

Next, using a soft toothbrush, gently scrub the white ring and the tips of the sensor (at bottom) with regular toothpaste. Any oil or calcium buildup should be scrubbed with a mild degreasing detergent. Once cleaned, you can rinse the probes with the clean water in your container. Replace Teflon tape (with new tape) and reinstall the sensors by hand tightening only. After reconnecting to the controller, you will need to manually test and balance your water.
