Drift outside it and elements you have already paid for stay locked in solution, and what looks like a deficiency is really a lockout. Colour drops and paper strips get you close but not close enough to spot a slow drift in a recirculating tank. A meter you trust turns feeding from guesswork into something you can repeat.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eCalibrate with fresh buffer solution before first use and regularly afterwards.\u003c\/li\u003e\n\u003cli\u003eRinse the electrode with clean water between readings, never wipe it dry.\u003c\/li\u003e\n\u003cli\u003eDip the probe into the mixed solution and wait for the reading to settle.\u003c\/li\u003e\n\u003cli\u003eAdjust with pH up or down, stir, then re-test rather than dosing twice.\u003c\/li\u003e\n\u003cli\u003eStore the electrode wet in storage solution, never dry.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eType\u003c\/th\u003e\n\u003ctd\u003eHandheld digital pH meter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRange\u003c\/th\u003e\n\u003ctd\u003e0.0 to 14.0 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAccuracy\u003c\/th\u003e\n\u003ctd\u003e±0.1 pH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCalibration\u003c\/th\u003e\n\u003ctd\u003eManual, one or two point\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtection Rating\u003c\/th\u003e\n\u003ctd\u003eIP65 waterproof\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery\u003c\/th\u003e\n\u003ctd\u003e4 x button cell, included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBattery Life\u003c\/th\u003e\n\u003ctd\u003eOver 1500 hours continuous\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eElectrode\u003c\/th\u003e\n\u003ctd\u003eReplaceable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e","brand":"Milwaukee","offers":[{"title":"Default Title","offer_id":53446971752714,"sku":null,"price":41.49,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/image1.jpg?v=1785315676","url":"https:\/\/hydrocropshop.co.uk\/products\/milwaukee-ph51-waterproof-ph-tester","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
