Commercial-Grade pH Monitoring for Precision Irrigation
The TrolMaster PPH-2 Heavy-Duty In-Tank pH Sensor is designed for growers who demand reliable, continuous monitoring of their nutrient solution. Built for commercial environments, the PPH-2 provides highly accurate pH readings, helping maintain the ideal nutrient balance for healthy root development, efficient nutrient uptake and stronger crop performance. Compatible with Aqua-X, Aqua-X Pro, Aqua-X Plus, Green-X and Tent-X systems (via the appropriate AMP Sensor Board), it delivers dependable monitoring throughout every irrigation cycle.
Unlike standard pH probes, the PPH-2 is engineered for long-term use in nutrient reservoirs and commercial irrigation systems. Its heavy-duty construction, 3.6-metre cable and BNC connection make installation straightforward while allowing flexible sensor placement. Whether you're growing tomatoes, peppers, herbs or leafy greens, maintaining a stable pH helps prevent nutrient lockout, reduce waste and maximise crop quality.
Frequently Asked Questions
What does the TrolMaster PPH-2 measure?
The PPH-2 continuously measures the pH level of your nutrient reservoir, allowing growers to monitor water quality and maintain the ideal conditions for healthy plant growth.
What's the difference between the PPH-1 and PPH-2?
The PPH-2 is a commercial-grade heavy-duty in-tank pH sensor, designed for more demanding growing environments where durability and long-term reliability are essential.
Which TrolMaster systems is the PPH-2 compatible with?
The PPH-2 is compatible with:
Aqua-X (NFS-1)
Aqua-X Pro (NFS-2)
Aqua-X Plus (NFS-3)
Green-X (GCS-1)
Tent-X (TCS-1)
using the appropriate AMP Sensor Board.
Do I need a Sensor Board?
Yes. The PPH-2 connects via a compatible AMP-2 or AMP-3 Sensor Board, depending on your TrolMaster controller. It cannot be connected directly to the controller.
Why is maintaining the correct pH important?
Correct pH allows plants to absorb nutrients efficiently. If the pH drifts outside the ideal range, nutrient lockout can occur, resulting in deficiencies, slower growth and reduced yields.
How should I store the pH probe?
Always keep the protective storage cap fitted and use the correct pH storage solution. If the probe dries out completely, it may no longer function correctly and may not be covered under warranty.
How long is the sensor cable?
The PPH-2 includes a 3.6-metre cable, giving growers plenty of flexibility when positioning the sensor in reservoirs or nutrient tanks.
Who is the PPH-2 designed for?
The PPH-2 is ideal for commercial growers, hydroponic systems, greenhouses and serious hobby growers looking for durable, accurate pH monitoring as part of a fully automated irrigation system.
