£129.95

The TrolMaster PPH-3 is a heavy-duty pH sensor designed for continuous monitoring of the acidity or alkalinity of liquid nutrient solutions, with a compact threaded design suitable for both drop-in reservoir monitoring and inline installation.

Developed for TrolMaster's nutrient monitoring systems, the PPH-3 features an improved sensing element designed to provide stable and reliable pH measurement. Its reduced-diameter protective sleeve and shorter body make installation easier in restricted spaces while the threaded construction allows the sensor to be fitted into a standard 3/4" PVC tee for inline monitoring.

The probe can also be used as a drop-in sensor for monitoring nutrient solution directly within a reservoir or tank. This gives growers the flexibility to choose an installation method appropriate to their irrigation and nutrient-management system.

A 3.6m cable provides flexible positioning, while the BNC connection allows the PPH-3 to connect directly to a compatible TrolMaster AMP-2 or AMP-3 Sensor Board.

Why choose the TrolMaster PPH-3?

  • Continuous nutrient-solution pH monitoring - measures acidity and alkalinity across the full pH 0-14 range.
  • Heavy-duty sensor design - developed for demanding nutrient and irrigation monitoring applications.
  • Improved sensing element - designed by TrolMaster for increased stability and reliable performance.
  • Drop-in or inline installation - use directly in a nutrient reservoir or integrate the probe into compatible pipework.
  • 3/4" PVC tee compatible - threaded compact body allows installation into a standard 3/4" PVC tee fitting.
  • Compact probe design - reduced length and diameter help the sensor fit into tighter installations.
  • 3.6m cable - provides flexibility when positioning the probe and sensor board.
  • BNC connection - connects directly to compatible TrolMaster AMP-2 and AMP-3 Sensor Boards.
  • Wide TrolMaster compatibility - suitable for several Aqua-X, Green-X and Tent-X control systems when paired with the correct sensor board.

Continuous pH monitoring of nutrient solutions

Maintaining an appropriate nutrient-solution pH is an important part of controlled irrigation and nutrient management. The PPH-3 allows a compatible TrolMaster controller to continuously monitor the pH of the solution rather than relying solely on occasional handheld measurements.

This makes it easier to identify changes in pH over time and provides a clearer picture of nutrient-solution conditions within the irrigation system.

When connected to the appropriate TrolMaster Sensor Board and controller, pH data becomes part of the wider TrolMaster monitoring system alongside compatible EC, temperature, irrigation and environmental sensors.

Drop-in or inline installation

Reservoir / drop-in monitoring

The PPH-3 can be positioned directly within the nutrient solution for straightforward reservoir monitoring. Its 3.6m cable provides flexibility when locating the probe in relation to the sensor board and controller.

Inline monitoring

The PPH-3 features a threaded body specifically designed to allow installation into a standard 3/4" PVC tee fitting. This allows the probe to monitor nutrient solution as part of an inline irrigation or nutrient-delivery system.

The reduced length and diameter of the PPH-3 make it particularly useful where installation space is limited.

TrolMaster controller compatibility

The PPH-3 connects to a compatible TrolMaster controller through an AMP-2 or AMP-3 Sensor Board. The required sensor board depends on the controller being used.

Aqua-X NFS-1 Compatible using AMP-2 Sensor Board
Aqua-X Pro NFS-2 Compatible using AMP-3 Sensor Board
Aqua-X Plus NFS-3 Compatible using AMP-3 Sensor Board
Green-X GCS-1 Compatible using AMP-3 Sensor Board
Tent-X TCS-1 Compatible using AMP-3 Sensor Board

Important pH probe care

A pH probe must not be allowed to dry out. TrolMaster specifies that the PPH-3 should be stored with its protective storage cap and the correct pH probe storage solution whenever it is not in use.

Allowing the sensing element to dry completely can permanently affect the operation of the probe. TrolMaster also states that probes returned without the storage cap and in a dry condition are not eligible for warranty coverage.

Proper cleaning, storage and calibration are therefore important parts of maintaining reliable pH monitoring performance.

TrolMaster PPH-3 pH Sensor FAQs

What does the TrolMaster PPH-3 measure?

The PPH-3 measures the pH of a liquid solution, indicating its acidity or alkalinity across a pH range of 0-14.

Is the PPH-3 designed for nutrient solutions?

Yes. The PPH-3 is specifically designed as a heavy-duty nutrient pH sensor and can be incorporated into compatible TrolMaster nutrient and irrigation monitoring systems.

Can the PPH-3 be placed directly in a reservoir?

Yes. The PPH-3 is drop-in compatible and can be used to monitor nutrient solution directly within a suitable reservoir or tank.

Can the PPH-3 be installed inline?

Yes. The threaded probe body allows the PPH-3 to be installed into compatible inline pipework for continuous nutrient-solution monitoring.

What size fitting does the PPH-3 use?

TrolMaster designed the threaded PPH-3 body to fit a standard 3/4" PVC tee fitting.

What is the measurement range of the PPH-3?

The PPH-3 has a specified measurement range of pH 0-14.

How accurate is the TrolMaster PPH-3?

TrolMaster specifies pH accuracy of ±0.2 pH for the PPH-3.

How does the PPH-3 connect to a TrolMaster controller?

The probe uses a BNC male connector and connects through a compatible AMP-2 or AMP-3 Sensor Board, depending on the controller.

Does the PPH-3 connect directly to an Aqua-X controller?

No. A compatible sensor board is required between the PPH-3 and controller. The Aqua-X NFS-1 uses the AMP-2, while compatible newer systems use the AMP-3.

How long is the PPH-3 cable?

The probe is supplied with a 3.6m cable, providing flexibility when positioning the sensor within a reservoir or irrigation installation.

Can a TrolMaster pH probe be allowed to dry out?

No. TrolMaster states that its pH probes must remain wet and should be stored using the supplied storage cap and appropriate pH probe storage solution. Allowing the sensing element to dry completely can damage the probe.

Does the PPH-3 measure EC?

No. The PPH-3 measures pH only. For EC and nutrient-solution temperature monitoring, TrolMaster offers the compatible PCT-series EC and temperature sensors.

What is the difference between the PPH-2 and PPH-3?

The PPH-2 is primarily designed as a heavy-duty in-tank pH sensor. The PPH-3 has a shorter, reduced-diameter threaded body specifically designed to support both drop-in and inline installation, including installation into a standard 3/4" PVC tee.

Which TrolMaster systems support the PPH-3?

The PPH-3 is compatible with Aqua-X NFS-1, Aqua-X Pro NFS-2, Aqua-X Plus NFS-3, Green-X GCS-1 and Tent-X TCS-1 when used with the appropriate AMP-2 or AMP-3 Sensor Board.
