{"product_id":"ac-infinity-ph-meter-kit","title":"AC Infinity pH Meter Kit","description":"\u003cp\u003eThe AC Infinity pH Meter Kit is the entry meter in AC Infinity's three-model water testing line, built for growers who want a dependable daily pH check without paying for laboratory-grade resolution. It reads pH and water temperature together from a single dip, resolving to ±0.1 pH, comfortably inside the margin that matters when steering a nutrient solution toward the 5.5 to 6.5 window where hydroponic feeds keep nutrients available. Growers chasing finer resolution or a replaceable electrode should step up to the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-ph-meter-pro-kit\" target=\"_blank\" title=\"AC Infinity pH Meter Pro Kit\" rel=\"noopener\"\u003eAC Infinity pH Meter Pro Kit\u003c\/a\u003e, while the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-all-in-one-meter\" target=\"_blank\" title=\"AC Infinity Hydroponic Meter PRO Kit (pH \u0026amp; EC)\" rel=\"noopener\"\u003eAC Infinity Hydroponic Meter PRO Kit (pH \u0026amp; EC)\u003c\/a\u003e extends the same platform to conductivity, TDS and salinity.\u003c\/p\u003e\n\u003cp\u003eAt its core is a lithium glass membrane probe protected by a detachable sensor shield that guards the glass bulb between tests and comes off for cleaning. The body is IP67 rated against dust and high-volume moisture, and at 17.8 x 4.2 x 3.0 cm (7.01 x 1.65 x 1.18 in) it is the slimmest meter in the family. Calibration is auto-recognising: the meter identifies whichever buffer the probe is dipped in, starting at pH 7.00 and following with 4.00, and each included buffer is good for up to 10 calibrations before replacement. A third point at pH 10.01 can be added for measuring above pH 8.0, though that solution is not included. In use, the probe sits at least 2.5 cm (1 in) deep in the sample, a smile icon confirms the reading has stabilised, and the LCD locks the value for reading away from the reservoir.\u003c\/p\u003e\n\u003cp\u003eThe kit ships complete, with the meter, one pH 4.00 buffer, one pH 7.00 buffer and a travel lanyard, and batteries arrive pre-installed behind a pull tab. Two limitations are worth knowing. The probe is fixed rather than replaceable, and AC Infinity's 2024 manual quotes an average electrode life of around 18 months depending on care, so maintenance protects the purchase: the probe is never stored in tap, RO or distilled water, the cap stays moist between sessions, and 3M KCL or pH 4.00 buffer handles long-term storage. Replacement buffers such as the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/bluelab-ph-buffer-7-2\" target=\"_blank\" title=\"Bluelab pH Calibration Solution 7.0\" rel=\"noopener\"\u003eBluelab pH Calibration Solution 7.0\u003c\/a\u003e keep calibration honest once the included pair is spent.
