Couldn't load pickup availability
Take complete, professional control over your liquid nutrient strength and water purity with the AC Infinity Hydroponic Meter PRO Kit. Engineered for serious growers, commercial facilities, and hydroponic setups, this multi-parameter digital meter measures 6 critical water quality metrics in seconds: pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS/PPM), Salinity, and Liquid Temperature.
Featuring an ultra-sensitive, replaceable lithium glass membrane probe, the AC-PHM7 delivers lab-grade readings with hyper-precise ±0.01 pH accuracy. Instead of throwing away the entire meter when a probe wears out over time, the detachable probe design lets you swap in a fresh sensor module in seconds. The unit carries an IP67 waterproof rating and comes fully loaded with a complete calibration set (4.00 pH, 7.00 pH, 1413 μS, 12.88 mS) plus 3M KCL storage solution to maximise sensor lifespan.
What Makes It Stand Out
-
6-in-1 Multi-Parameter Testing: Measures pH, EC, TDS, Salinity, and Temperature on a single, crisp backlit digital display.
-
Replaceable Sensor Probe: Detachable probe design allows you to easily replace worn sensors, extending the lifetime of the meter and saving long-term replacement costs.
-
Pinpoint ±0.01 pH Precision: High-response lithium glass membrane delivers fast, lab-grade readings for delicate nutrient solutions.
-
Fully Loaded Calibration Suite: Includes 4.00 pH, 7.00 pH, 1413 μS/cm, and 12.88 mS/cm buffer solutions for full multi-point calibration, plus 3M KCL storage liquid.
-
Rugged IP67 Waterproof Build: Sealed housing prevents water damage from full submersion, harsh chemicals, dust, and humid grow room conditions.
-
Protective Probe Shield: Integrated guard shields the sensitive glass bulb against impact damage when mixing solutions or taking reservoir readings.
