This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration. pH 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\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003e\u003cspan\u003eCleaning is a fast and effective routine that should be performed on a regular basis as a preventative measure against using a dirty electrode and to ensure that the junction is not clogged. By simply immersing the electrode in the HI7061L cleaning solution for 15 to 20 minutes will dissolve any mineral deposits or other coatings.  \u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eAir tight bottle with tamper-proof seal\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eEnsures quality and freshness of solution\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eEach bottle marked with lot number and expiration date.\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli dir=\"ltr\"\u003e\n\u003cp dir=\"ltr\"\u003e\u003cspan\u003eHanna cleaning solutions are specially formulated to have an expiration of 5 years from manufacture for an unopened bottle.\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eCertificate of Analysis: no\u003cbr\u003ePackage: bottle\u003cbr\u003eQuantity: 1\u003cbr\u003eSize: 500 mL\u003c\/p\u003e","brand":"Hanna","offers":[{"title":"Default Title","offer_id":46714401226904,"sku":"HI7061L","price":24.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0616\/0950\/9016\/files\/hi7061l.jpg?v=1750275005","url":"https:\/\/thepetsource.ca\/products\/hanna-general-purpose-cleaning-solution-500-ml-hi7061l","provider":"The Pet Source","version":"1.0","type":"link"}
