TrolMaster Sensor Board (AMP-3)

The TrolMaster Sensor Board (AMP-3) connects compatible pH and EC/temperature sensors to supported TrolMaster irrigation and environmental control systems.

It acts as the communication bridge between the nutrient sensors and the main controller, allowing you to monitor pH, EC, and water temperature readings directly on the AMP-3 LCD display and the controller.

Monitor pH, EC and Water Temperature

When connected to compatible TrolMaster probes, the AMP-3 provides centralized monitoring of:

  • pH
  • Electrical conductivity (EC)
  • Water temperature

This makes it useful for monitoring nutrient reservoirs, irrigation solutions, and other water-management applications.

Compatible with pH and EC/Temperature Sensors

The AMP-3 supports compatible TrolMaster nutrient sensors, including:

  • PPH-1 Reservoir pH Sensor
  • PPH-2 Heavy-Duty Reservoir pH Sensor
  • PPH-3 Heavy-Duty Inline pH Sensor
  • PCT-1 Reservoir EC/Temp Sensor
  • PCT-2 Heavy-Duty Reservoir EC/Temp Sensor
  • PCT-3 Heavy-Duty Inline EC/Temp Sensor

The sensor board connects these probes to the compatible TrolMaster controller.

LCD Display and RJ12 Connection

The integrated LCD display lets you view readings directly on the sensor board.

A standard RJ12 connection links the AMP-3 to the main controller, while the addressing button identifies multiple compatible sensor boards within larger monitoring systems.

  • Integrated LCD display
  • RJ12 communication
