This package is the basic aquarium controller kit in a DIY PCB format for greatest savings. There are 5 connectors and a 4-pin header that you will need to solder to the controller board.

You can download the 3D case files to print them.

The controller has a fully isolated pH circuit built in, simply plug in any pH probe with a BNC connector and you're ready to accurately monitor your pH, probe is not included.

Package Includes

• Controller PCB circuit board
• Controller faceplate
• 5 pluggable screw terminal connectors

Parts Required

• 12v - 24v DC power supply (2 amps or more)
  

If you want to monitor pH you need a probe - EXAMPLE
