Sensor Pair, Bed Level and Nutrient Level (Included with Starter Kit)

This Sensor Pair is designed to work with all Growers’ Gizmos Hydroponic Controllers. The Nutrient Level Sensor has a green stripe. Otherwise both sensors are the same. They are submersible and contain a resistance that allows the controller to detect the proper connections of both sensors.

• Includes 6 ft of cable on each sensor
• Shrouded body to protect electrodes

This sensor Pair is included with the starter kit. The tips can be cleaned with a brush. The only reason to order another pair is for another grow bed and controller or as a replacement.
