The TrolMaster AMP-3 is a dedicated sensor interface/bridge board for the Aqua-X Pro NFS-2 controller, connecting external pH and EC/temperature probes to the irrigation control system. It provides an onboard 1-inch LCD display for local monitoring while simultaneously sending pH, EC, and water-temperature readings to the NFS-2 controller. Multiple AMP-3 boards can be connected for monitoring multiple reservoirs or nutrient systems.
