That resolution suits growers holding tight reservoir targets, dialling in stock solutions, or chasing the slow drift a coarser meter would round away.\u003c\/p\u003e\n\u003cp\u003eIts defining feature is the interchangeable lithium glass membrane probe. Rather than the electrode's lifespan retiring the whole instrument, the probe ring unscrews and the electrode pulls straight off its pins - never twisted, which bends them - so a fresh probe seats, soaks in 3M KCL for 5 to 15 minutes and calibrates back to full accuracy. Around it sits an IP67-rated body measuring 17.8 x 4.2 x 3.3 cm (7.01 x 1.65 x 1.30 in), with a backlit LCD carrying a battery indicator, an AUTO-HOLD function that freezes any reading held stable for more than ten seconds, low and high alarms settable anywhere from 0 to 14.00 pH, and a dedicated mV mode reporting raw electrode output. Calibration auto-recognises up to five points - 1.68, 4.00, 7.00, 10.01 and 12.45 - always beginning at 7.00; the included 4.00 and 7.00 buffers each cover about 10 calibrations and the 10.01 about five.\u003c\/p\u003e\n\u003cp\u003eThe kit is the most complete in the family, containing the meter, a travel lanyard, pH 4.00, 7.00 and 10.01 buffers, 3M KCL soaking solution and three calibration vials that keep each buffer uncontaminated during calibration. The KCL doubles as probe first aid: a two-hour soak restores a dried or sluggish electrode, a quarter-cap stores the probe long term, and refills such as the \u003ca href=\"https:\/\/www.hydrooasis.com.au\/products\/bluelab-kci-ph-storage-1\" target=\"_blank\" title=\"Bluelab KCI pH Storage Solution\" rel=\"noopener\"\u003eBluelab KCI pH Storage Solution\u003c\/a\u003e keep that regime running for the life of the meter. One boundary remains: the Pro reads pH only, so checking solution strength still calls for an EC instrument. With a swappable electrode and calibration spanning 1.68 to 12.45, it holds ±0.01 accuracy across years of reservoir work rather than a single electrode's lifespan.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eNOTE:\u003c\/strong\u003e despite the IP67 rating, AC Infinity instruct that the meter must not be fully submerged - immerse the probe end only. Calibration solutions are not for consumption; wash hands after handling and keep all solutions away from children and pets.\u003c\/em\u003e\u003c\/p\u003e","brand":"AC Infinity","offers":[{"title":"Default Title","offer_id":45953077674142,"sku":"819137023987","price":169.99,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0709\/5261\/6094\/files\/AC_Infinity_pH_Meter_Kit_Pro_375ebdc0-6b15-4085-890a-8ee210baf628.png?v=1784723060","url":"https:\/\/www.hydrooasis.com.au\/products\/ac-infinity-ph-meter-pro-kit","provider":"Hydro Oasis","version":"1.0","type":"link"}
