TrolMaster Aqua-X Reservoir pH Sensor (PPH-1) – pH Probe

Continuous reservoir pH, not guesswork

The TrolMaster PPH-1 Reservoir pH Sensor continuously monitors the pH of your nutrient reservoir when running the Aqua-X irrigation control system, replacing occasional spot checks with a live reading fed straight to the controller. Because pH governs how well plants can actually absorb the nutrients in solution, holding it steady matters as much as mixing the feed correctly. A long probe cable allows flexible placement inside the reservoir while the Aqua-X controller logs readings in real time, so you can track trends and correct drift before it hits root health, vegetative growth or flowering.

Key Benefits

• Continuous reservoir pH monitoring integrated with the Aqua-X system
• Real-time data logging to track pH trends and spot drift early
• Long probe cable for flexible placement in nutrient reservoirs
• Supports efficient nutrient uptake by keeping pH in the optimal range
• Promotes stronger root development and prevents nutrient lockout
• App and controller monitoring for hands-off oversight of the tank

Nutrients in the tank but deficiencies on the plants?

Incorrect pH is one of the most common causes of nutrient deficiencies and lockout in hydroponics. Even with a fully charged reservoir, plants cannot take up elements properly once pH drifts outside the optimal band. The PPH-1 shows reservoir pH in real time through Aqua-X, so changes are caught and corrected quickly, keeping the solution stable and preventing slow veg or weak flowering.

How to Use

1. Connect the PPH-1 sensor to the TrolMaster AMP-2 sensor board.
2. Connect the AMP-2 board to the Aqua-X irrigation control system.
3. Place the pH probe directly into the nutrient reservoir.
4. Keep the probe fully submerged for accurate readings.
5. Monitor pH through the Aqua-X controller or TrolMaster mobile app.
6. Adjust the nutrient solution as needed to hold your target pH range.
