Maintaining exact pH levels in your nutrient reservoir or irrigation water is essential for preventing nutrient lockouts and ensuring rapid root absorption. The AC Infinity pH Meter PRO Kit (AC-PHM5) is a high-precision digital water tester designed specifically for growers, hydroponic gardeners, and water treatment applications.
Equipped with an interchangeable lithium glass membrane probe, the AC-PHM5 measures pH and solution temperature instantly with an impressive ±0.01 pH accuracy. Built for long-term reliability, the probe assembly can be unscrewed and replaced when worn down over years of use, saving you from replacing the entire unit. It features an IP67 waterproof and dustproof rating, an integrated probe guard, and comes complete with a full 3-point calibration set (4.00 pH, 7.00 pH, 10.01 pH) plus 3M KCL storage fluid to keep the sensor glass hydrated and responsive.
What Makes It Stand Out
-
Pinpoint ±0.01 pH Accuracy: Fast-acting lithium glass membrane delivers instant, highly stable pH and temperature readings.
-
Replaceable Sensor Module: Features a detachable probe head that unscrews easily, extending the service life of your meter and lowering long-term maintenance costs.
-
Full 3-Point Calibration Kit: Comes with 4.00 pH, 7.00 pH, and 10.01 pH buffer solutions for full-range calibration across acidic and alkaline water profiles.
-
3M KCL Storage Solution Included: Includes dedicated KCL storage liquid to hydrate the glass bulb between uses, preserving response speed and accuracy.
-
IP67 Sealed Waterproof Design: Built to withstand accidental submersion, high-humidity grow tents, and harsh chemical environments.
-
Rugged Sensor Guard: Protective cage surrounds the delicate glass membrane to shield it from accidental bumps against reservoir walls or mixing containers.
