Sensor Board to connect sensors to NFS-2 controller

Multi-Zone pH & EC Sensor Bridge for Aqua-X Pro

Monitoring pH and EC across several reservoirs or fertigation zones from a single controller usually means checking a shared display screen for each one, which slows things down as the number of zones grows. The AMP-3 sensor board solves that with an onboard LCD that shows live status at the board itself, plus multi-unit addressing that lets several AMP-3 boards report back to one Aqua-X Pro or Plus controller.

It acts as a bridge between pH and EC/temperature sensors and the Aqua-X Pro or Plus controller line specifically, useful for fertigation setups monitoring more than one reservoir or zone at once.

Key Features & Benefits

• pH & EC/Temperature Bridging — connects sensor probes to an Aqua-X Pro or Plus controller.
• Onboard LCD Display — checks live status directly at the sensor board.
• Multi-Unit Addressing — connects multiple AMP-3 boards to one controller for several zones.
• Aqua-X Pro/Plus Compatible — built specifically for the Aqua-X Pro and Plus controller line.

Who Should Use the AMP-3 Sensor Bridge

Growers running an Aqua-X Pro or Plus controller across multiple reservoirs or fertigation zones, who want one AMP-3 board per zone bridging readings back to the main controller, will find the AMP-3 suited to that setup.

About TrolMaster

TrolMaster's Aqua-X irrigation-control line, part of the company's broader platform out of Sacramento, California, uses addressable sensor boards like the AMP-3 to scale pH and EC monitoring across multiple fertigation zones from one Pro or Plus controller.

Frequently Asked Questions

How many AMP-3 boards can connect to one controller?

Multiple boards can be addressed individually on a single Aqua-X Pro or Plus controller, supporting several zones at once. Each board reports its own readings independently through that shared connection.

Does the AMP-3 have its own display?

Yes, an onboard LCD shows live sensor status at the board itself, without needing to check the main controller screen. That's a difference from boards that only report data back to a central display.

What controllers is the AMP-3 compatible with?

The Aqua-X Pro and Plus controller line specifically, rather than TrolMaster's broader controller catalog. Confirm the exact controller model before ordering to ensure compatibility.

What does the AMP-3 connect?

pH and EC/temperature sensor probes, bridging their readings to the connected controller. It's built for fertigation setups monitoring more than one reservoir or zone.
