Who This Is For
- You are integrating reservoir monitoring because your manual spot checks keep missing the pH drift that stresses your crop.
- You are connecting to a central controller because you need live alerts to fix nutrient imbalances before plant uptake drops.
What We Found
- The 3.6 metre cable is a massive win because it lets you tuck the controller away from any water spray zones.
- We tell everyone that the BNC terminal connection is rock solid and never needs the fiddling that older probes require.
What Users Say
- Growers who integrated the sensor into their automated system say they stopped losing hours every morning on manual testing.
- Managers who moved to real-time alerts report they no longer find their reservoir out of balance after a long weekend.
TrolMaster PPH-1 Reservoir pH Sensor
pH is one of the first things to drift in a nutrient reservoir — and one of the last things growers check manually until something goes wrong. The TrolMaster PPH-1 Reservoir pH Sensor connects directly to the AMP-2 sensor board via BNC terminal, feeding live pH readings into your TrolMaster Aqua-X NFS-1 Irrigation Control System so you can monitor and respond to changes before they affect plant uptake. For a complete reservoir profile, it is often paired with the TrolMaster PCT-1 Environmental Control EC sensor to track both acidity and nutrient concentration. Its 3.6-meter cable provides flexible placement around the reservoir without requiring extensions, and its range of compatible applications extends beyond irrigation to aquariums, laboratories, and any environment where consistent water pH matters.
The PPH-1 is the reservoir drop-in version of TrolMaster's pH probe lineup — for inline plumbing installation in ¾" PVC tee fittings, see the PPH-3.
Compatibility: TrolMaster Aqua-X NFS-1 (via AMP-2), Green-X (GCS-1 via AMP-2), and Tent-X (TCS-1 via AMP-2)
⚠️ pH probes must be stored with the protective storage cap in place and filled with the correct probe storage solution at all times. Allowing the probe tip to dry out completely will permanently damage the sensor element and void warranty coverage. Never store the PPH-1 dry or submerged in plain water.
What's Included
Features
🧪
Reservoir pH Monitoring
Drop-in reservoir probe tracks live pH levels and passes readings to the TrolMaster controller via AMP-2 — monitor and respond to drift before it affects plant uptake.
🔌
BNC Direct Connection
BNC terminal connects directly to the AMP-2 sensor board — no additional adapters or converters required for a clean, secure signal path.
🌐
Wide Application Range
Suitable for hydroponics, aquariums, and labs. If your system requires a different probe specification, the TrolMaster PPH-2 Environmental Control sensor is also available for specific TrolMaster configurations.

Support & Manuals
Warranty
TrolMaster backs the PPH-1 with a 3-year warranty from the original date of purchase, covering all mechanical and electronic components under normal operating conditions. Components that fail due to abnormal or improper usage are excluded from this coverage.
Important — pH probe storage requirement: pH probes must be stored with the protective storage cap in place and filled with the correct probe storage solution at all times. A probe that is allowed to dry out completely will permanently damage the sensor element and is explicitly excluded from warranty coverage. Any probe returned without the storage cap or in a dried-out state will not be eligible for a warranty claim.
FAQs
What does the PPH-1 measure?
The PPH-1 measures the pH level of water in a reservoir. When connected to an AMP-2 sensor board, the reading is passed to the TrolMaster controller and displayed on both the sensor board's LCD and the master controller screen simultaneously — giving you real-time oversight of pH levels without manual testing.
What is the difference between the PPH-1 and the PPH-3?
Both probes measure pH and use a BNC terminal connection, but they differ in installation capability and sensor board compatibility. The PPH-1 is a reservoir drop-in probe compatible with the AMP-2 board. The PPH-3 is a redesigned version with a reduced-diameter sleeve and threaded body that also fits directly into standard ¾" PVC tee fittings for inline plumbing installation, and is compatible with both AMP-2 and AMP-3 boards. If you need inline measurement or AMP-3 compatibility, the PPH-3 is the appropriate choice.
Which sensor boards and controllers is the PPH-1 compatible with?
The PPH-1 is compatible with the AMP-2 sensor board, which is used with the TrolMaster Aqua-X NFS-1 Irrigation Control System. It connects via BNC terminal directly to the AMP-2 with no additional adapters. For setups using AMP-3-based controllers like the TrolMaster Aqua-X NFS-2 or the Aqua-X NFS-3 Irrigation Control System, the PPH-3 is the compatible pH probe.
Can the PPH-1 be used for applications other than irrigation?
Yes — while the PPH-1 is designed for integration with TrolMaster irrigation and environmental control systems, it is equally suitable for aquarium monitoring, laboratory water quality measurement, and advanced grow room management using the TrolMaster Hydro-X HCS-2 Grow Tent Control with the appropriate interface.
How should I store the PPH-1 when it's not in use?
pH probes must always be stored with the protective storage cap in place and filled with the correct probe storage solution. Allowing the probe tip to dry out completely will permanently damage the sensor element and void warranty coverage. Never store the PPH-1 dry or submerged in plain water — only the designated probe storage solution maintains the sensor's integrity between uses.
Does the PPH-1 warranty cover probes that have dried out?
No. Probes returned without the storage cap in place or in a dried-out condition are explicitly excluded from warranty coverage. pH probe longevity depends entirely on proper wet storage — this applies both between active measurements and during any period the probe is removed from the system.
How long is the PPH-1 cable — is it enough for most reservoir setups?
The PPH-1 includes a 3.6-meter (approximately 12-foot) cable, which is sufficient for most reservoir-based setups where the AMP-2 sensor board is mounted nearby. For installations requiring greater separation between the probe and the sensor board, cable extension options should be considered.
