Who This Is For
- You are adding centralized sensor nodes because manually checking pH and EC in every reservoir wastes hours of your week
- You are building out a multi-zone system because you need to track nutrient levels independently across different reservoirs
What We Found
- We recommend mounting these near the reservoir edge because the short cable lengths require tight positioning
- The LCD screen is a massive upgrade over blind controllers because you can verify readings while standing in the room
What Users Say
- Growers who integrated these into their irrigation setups say they stopped dealing with nutrient drift surprises
- Operators who added these to their existing master controllers report that troubleshooting water quality is now instant
TrolMaster AMP-3 pH, EC & Temp Sensor Board
Manually checking water quality across multiple reservoir zones is a slow, inconsistent process that often leads to errors at critical moments. The TrolMaster AMP-3 Environmental Control sensor board solves this by acting as a high-precision bridge, connecting your pH and EC/Temperature sensors directly to your central controller. This ensures you receive real-time, accurate data without the guesswork, allowing you to maintain perfect nutrient balance and water health.
Designed for professional-scale operations, the AMP-3 delivers live readings for three vital parameters simultaneously on its integrated LCD screen and your master controller. This modular system allows for easy upgrades and maintenance, as compatible probes connect separately to the board. By integrating the AMP-3 into your setup, you gain centralized oversight of your water quality, whether you are using the TrolMaster Green-X GCS-1 Greenhouse Control or the TrolMaster Tent-X TCS-1 Grow Tent Control.
Compatibility: TrolMaster Aqua-X Pro, Green-X, and Tent-X Systems

FAQs
No — the AMP-3 is a sensor board that acts as a bridge between compatible pH and EC/Temperature probes and the TrolMaster controller. This modular design allows you to pair the AMP-3 with the specific sensors suited to your system.
Once connected to compatible sensors, the AMP-3 reads and displays three parameters: pH level, electrical conductivity (EC), and water temperature. Readings appear on the integrated LCD and your master controller in real time.
Yes. The AMP-3 features an onboard addressing key that allows multiple units to be connected and individually identified within the same system, enabling independent monitoring across separate reservoirs or feed lines.
pH controls nutrient availability, EC measures nutrient concentration, and water temperature affects uptake efficiency. Tracking all three provides the earliest warning of imbalances before they impact plant health.
The AMP-3 connects to your TrolMaster controller via the included RJ12 cable. It includes both a 16ft and 4ft cable plus a T-shaped splitter for flexible installation.
