£113.95

The TrolMaster PPH-2 is a commercial-grade, heavy-duty pH probe designed for continuous monitoring of nutrient solution within reservoirs and water tanks.

Used with a compatible TrolMaster AMP-2 or AMP-3 Sensor Board, the PPH-2 provides continuous pH monitoring as part of a TrolMaster irrigation and nutrient-management system. This allows growers to keep track of changes in nutrient-solution acidity or alkalinity without relying solely on periodic handheld measurements.

The PPH-2 is designed primarily for in-tank use, making it particularly suitable for nutrient reservoirs, irrigation tanks and other liquid-monitoring applications. A generous 3.6m cable provides flexibility when positioning the probe in relation to the sensor board and controller.

Once connected through the appropriate TrolMaster Sensor Board, pH information can be displayed through the compatible controller and TrolMaster app. Minimum and maximum limits can also be configured within supported systems to provide notifications when pH moves outside the required range.

Why choose the TrolMaster PPH-2?

  • Continuous pH monitoring - monitor changes in nutrient-solution pH throughout the day.
  • Commercial-grade probe - heavy-duty sensor designed for demanding water and nutrient monitoring applications.
  • Designed for reservoir use - intended to be positioned directly within a water or nutrient tank.
  • TrolMaster integration - connects through a compatible AMP-2 or AMP-3 Sensor Board.
  • Remote monitoring capability - compatible connected TrolMaster systems can display sensor information through the TrolMaster app.
  • High and low pH alerts - compatible controllers can provide notifications when readings move outside configured limits.
  • 3.6m cable - provides flexibility when positioning the probe and sensor board.
  • BNC connection - provides direct connection to the pH input on the appropriate TrolMaster Sensor Board.
  • Wide application range - suitable for nutrient reservoirs and other compatible water-monitoring applications.

Continuous nutrient solution pH monitoring

Nutrient-solution pH can change as water is added, nutrients are mixed, plants take up nutrients and the reservoir conditions develop over time. The PPH-2 allows these changes to be monitored continuously through a compatible TrolMaster control system.

Continuous monitoring provides a much clearer picture of reservoir conditions than occasional spot checks alone. It can help growers identify unexpected pH movement and respond before the solution moves too far outside the desired operating range.

When used with a compatible connected TrolMaster controller, pH readings can form part of the wider irrigation monitoring system alongside EC, nutrient-solution temperature, water-content and irrigation data.

Designed for in-tank monitoring

TrolMaster specifies the PPH-2 as a heavy-duty in-tank pH sensor. The probe is intended to be positioned within the water or nutrient reservoir being monitored, while the 3.6m cable provides flexibility when locating the associated sensor board.

For new installations requiring a dedicated threaded probe for either reservoir or inline pipework installation, the newer TrolMaster PPH-3 provides an alternative design. The PPH-2 remains an excellent choice where a heavy-duty reservoir probe is required.

TrolMaster system compatibility

The PPH-2 does not connect directly to the main controller. It connects through the appropriate TrolMaster AMP Sensor Board, which then communicates the pH reading to the controller.

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

Never allow the PPH-2 pH probe to dry out completely. TrolMaster specifies that its pH probes must be stored using the storage cap and the correct probe storage solution.

If the sensing element is allowed to dry completely, the probe may no longer function correctly. TrolMaster also states that pH probes returned without the storage cap and in a dry condition are not eligible for warranty coverage.

Correct storage, routine cleaning and regular calibration are therefore important for maintaining reliable pH measurement.

TrolMaster PPH-2 pH Sensor FAQs

What does the TrolMaster PPH-2 measure?

The PPH-2 continuously monitors the pH of water or nutrient solution when connected to a compatible TrolMaster Sensor Board and controller.

Is the PPH-2 designed for nutrient reservoirs?

Yes. TrolMaster currently describes the PPH-2 as a heavy-duty in-tank pH sensor intended to be placed within a water or nutrient reservoir.

Is the PPH-2 a commercial-grade probe?

Yes. TrolMaster specifies the PPH-2 as a commercially rated probe for continuous pH monitoring.

Does the PPH-2 connect directly to the Aqua-X?

No. The probe connects through a compatible Sensor Board. The Aqua-X NFS-1 uses the AMP-2, while compatible newer TrolMaster controllers use the AMP-3.

Does the PPH-2 work with the AMP-3?

Yes. TrolMaster currently lists the PPH-2 as compatible with both AMP-2 and AMP-3 Sensor Boards, depending on the controller being used.

How long is the PPH-2 cable?

The PPH-2 is supplied with a 3.6m cable, providing flexibility when positioning the probe within a reservoir.

What connector does the PPH-2 use?

The PPH-2 uses a BNC connection for connection to the pH input on a compatible TrolMaster Sensor Board.

Can I monitor the PPH-2 through the TrolMaster app?

When the probe is connected through the appropriate Sensor Board to a compatible internet-connected TrolMaster controller, sensor data can be viewed through the TrolMaster system and app.

Can the system warn me about high or low pH?

Yes. Compatible TrolMaster systems allow minimum and maximum pH limits to be configured and can provide notifications when readings move outside those limits.

Can the PPH-2 be allowed to dry out?

No. The sensing element must remain hydrated. Store the probe with its protective cap and the correct pH probe storage solution whenever it is not in use.

Does the PPH-2 measure EC or water temperature?

No. The PPH-2 is a pH sensor. EC and nutrient-solution temperature require a compatible TrolMaster PCT-series EC/temperature sensor.

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

The PPH-2 is TrolMaster's heavy-duty in-tank pH probe. The newer PPH-3 uses a shorter, reduced-diameter threaded body designed for both reservoir and inline installation, including fitting into a standard 3/4" PVC tee.

Which controllers are compatible with the PPH-2?

TrolMaster currently lists the PPH-2 for use 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 paired with the appropriate AMP-2 or AMP-3 Sensor Board.

Is the PPH-2 suitable for continuous monitoring?

Yes. Continuous pH monitoring is the primary purpose of the PPH-2 when integrated with a compatible TrolMaster water and nutrient monitoring system.
