By simply immersing the electrode in the HI-7061-012 cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.\u003c\/p\u003e\n\u003cp\u003eElectrodes can become dirty from use and will produce inaccurate results even if they read correctly in a pH buffer.\u003c\/p\u003e\n\u003cp\u003eThe most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note because, during calibration, the instrument assumes that the electrode is clean and that the standardisation curve created during the calibration process will remain a valid reference until the next calibration.\u003c\/p\u003e\n\u003cp\u003epH meters on the market today will allow an offset voltage of approximately ±60 mV. The deviation from 0 mV is not unusual but ideally should be no greater than ±30 mV. The calibration process compensates for the change in offset voltage. If the mV offset continues to deviate and the meter is calibrated with a dirty electrode then inaccurate readings will result.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOther Hanna Groline Products\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-cleaning-solution-for-ph-electrodes-120ml\"\u003eCleaning Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-quick-cal-for-phec-120ml\"\u003eQuick Calibration for pH and EC\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-storage-solution-for-ph-electrodes-120ml\"\u003eStorage pH Solution\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-ph-tester-hi-98115\"\u003e98115 pH Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ph-temperature-tester\"\u003e98118 pH\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-instruments-groline-waterproof-ecppm-tester\"\u003e98318 EC\/TDS\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-phectdstemperature-meter-hi-9814\"\u003e9814 pH\/EC\/TDS Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.thehydrobros.com\/products\/hanna-groline-monitor-hi-981420\"\u003e981420 pH\/EC\/Temperature Meter\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HANNA","offers":[{"title":"Default Title","offer_id":43823461269719,"sku":"8470","price":11.4,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0561\/9092\/7032\/files\/nutrient-mangement-hanna-groline-cleaning-solution-for-ph-electrodes-120ml-39154677940439.png?v=1684515187","url":"https:\/\/www.thehydrobros.com\/vi\/products\/hanna-groline-cleaning-solution-for-ph-electrodes-120ml","provider":"The Hydro Bros","version":"1.0","type":"link"}
