Heavy Duty Nutrient pH Sensor, drop-in/in-line compatible

Wire a Single-Purpose pH Probe Into a Narrow PVC Tee

Some plumbing runs are tight enough that even a standard-diameter commercial probe won't seat properly, which is where a reduced-diameter, single-purpose design earns its keep. The TrolMaster PPH-3 reports pH alone from a slimmer probe body, dropping in or installing inline through a standard 3/4-inch PVC tee fitting where the larger PPH-2 wouldn't physically fit.

A threaded body keeps the reading stable once mounted, and either the AMP-2 or AMP-3 sensor board can host the connection through its 3.6-meter cable and BNC terminal.

Key Features & Benefits

• Slim, Single-Purpose pH Body — reports pH only, sized for tight plumbing runs.
• 3/4-Inch PVC Tee Compatible — drops in or installs inline through a standard fitting.
• Threaded Mount for Stability — keeps readings steady once the probe is seated.
• Works with AMP-2 or AMP-3 — connects to either sensor board on an Aqua-X system.
• 3.6-Meter BNC Cable — reaches the controller from a tight plumbing location.

Who Should Use the PPH-3 pH Sensor

Commercial growers whose plumbing tap point is too narrow for the standard-diameter PPH-2, but who still want pH reported as its own dedicated reading, are the intended users of the PPH-3. It trades a slightly shorter cable for a slimmer body that fits where the PPH-2 physically can't.

About TrolMaster

The PPH-3 is TrolMaster's answer to space-constrained plumbing runs within its single-purpose pH sensor line, engineered at the company's Sacramento, California headquarters for tap points a standard-diameter probe can't reach. Supporting both the AMP-2 and AMP-3 boards keeps it usable regardless of which sensor board generation a given Aqua-X system runs.

Frequently Asked Questions

Why choose the PPH-3 over the PPH-2?

Its reduced-diameter sleeve fits into tighter plumbing spaces than the PPH-2's standard body. Choose the PPH-3 specifically when the fitting or tap point is too narrow for the larger sensor.

Does the PPH-3 measure EC as well as pH?

No, it's a dedicated pH-only probe. Growers who need EC from the same tight tap point should check TrolMaster's PCT-3 sensor instead.

What sensor boards work with the PPH-3?

Either the AMP-2 or AMP-3 board on an Aqua-X controller. Either one can host the connection without additional hardware.

How long is the PPH-3's cable?

3.6 meters, terminated in a BNC connector. That's somewhat shorter than the 6-meter cable on the PPH-1 and PPH-2.

How does the threaded body help this sensor?

It keeps the probe seated firmly once mounted in the PVC tee fitting. A loose-fitting probe can drift out of position and throw off readings, which the threading is meant to prevent.
