TrolMaster Heavy-Duty Inline Nutrient pH Sensor (PPH-3) Next-Generation Inline pH Probe for Hydroponics, Irrigation, Aquaculture & Laboratory Use The TrolMaster PPH-3 Heavy-Duty Inline Nutrient pH Sensor is an upgraded, high-performance pH probe engineered for precise and reliable monitoring of nutrient solution acidity. Designed for professional growers and advanced environmental control systems, the PPH-3 features a refined sensor architecture, improved stability, and enhanced durability—making it ideal for continuous, real-time pH monitoring in demanding applications. The newly improved design includes a reduced-diameter protective sleeve and a threaded body, allowing the probe to be installed directly into standard 3/4-inch PVC tee fittings for inline sensing. This makes the PPH-3 an excellent choice for automated hydroponic systems, recirculating fertigation lines, aquaculture installations, and controlled laboratory environments. Compatible with both AMP-2 and AMP-3 nutrient sensor board modules, the PPH-3 integrates seamlessly with Aqua-X, Aqua-X Pro/Plus, Green-X, and Tent-X control systems to support fully automated nutrient management and environmental controls. Compatibility The PPH-3 works with the following TrolMaster sensor boards: Aqua-X (NFS-1) → AMP-2 Aqua-X Pro (NFS-2) → AMP-3 Aqua-X Plus (NFS-3) → AMP-3 Green-X (GCS-1) → AMP-3 Tent-X (TCS-1) → AMP-3 Key Features ✔ Heavy-Duty pH Probe with Enhanced Stability Upgraded sensor element provides more consistent, reliable performance for long-term inline monitoring. ✔ Inline or Drop-In Installation Threaded body fits standard 3/4" PVC tee fittings, making integration easy in irrigation and hydroponic systems. ✔ Long 3.6m Cable for Flexible Setup Allows placement in remote tanks, reservoirs, or inline plumbing without extension cables. ✔ BNC Connector for Direct Sensor Board Connection Plug-and-play compatibility with AMP-2 and AMP-3 modules. ✔ Wide Application Range Suitable for: Hydroponics & aeroponics Greenhouse fertigation Aquariums & aquaculture Water treatment Laboratory research ✔ Proper Storage Requirement To maintain accuracy and longevity, the probe must always be stored with the storage cap and correct storage solution.Dry probes are not eligible for warranty.
