Installation Method

The EC-1 sensor is meant to be fully submerged in your tank/reservoir. You can use the 3/4" NPT threading for inline installation. When mounting make sure the positioning allows the tip of the sensor to remain fully submerged and in a spot where it won't get bumped/knocked around.

Use and maintenance

Your sensor(s) will need periodic cleaning and calibration. The maintenance cycle can vary depending on your environment. To ensure you receive a long life from your sensor, please follow proper use/maintenance instructions.

Proper cleaning:

  1. Remove plastic cap from the tip of the sensor and run under fresh tap water (Do not use distilled, de-ionized, or reverse osmosis water).

  2. Fill a small container with clean tap water.

  3. Add a small amount of probe cleaner or mild dishwashing liquid.

  4. Gently stir sensor in solution. *Make sure you don't knock/bump the sensor off the sides of container to avoid damage*

Incorrect usage of this sensor voids our warranty.
