This probe is a direct replacement for the EC probe on MultiGrow (wires into an EpMT/Remote Sensor Box). This is also the same EC probe that is hardwired to an EC Mini Controller.

With an accurate EC sensor, you can measure the salinity of water and concentration of nutrients in your soil and ensure that each of your crops is getting the right amount of nutrients it needs. The Autogrow EC probe gives you insight into what your plants need to thrive.

Wire Configuration: Green, Brown, Blue
