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\/p\u003e\n\u003cp\u003e\u003cimg style=\"width: 528px;\" src=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=528\u0026amp;name=electrode-cleaning-illustration.gif\" sizes=\"(max-width: 528px) 100vw, 528px\" srcset=\"https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=264\u0026amp;name=electrode-cleaning-illustration.gif 264w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=528\u0026amp;name=electrode-cleaning-illustration.gif 528w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=792\u0026amp;name=electrode-cleaning-illustration.gif 792w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=1056\u0026amp;name=electrode-cleaning-illustration.gif 1056w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=1320\u0026amp;name=electrode-cleaning-illustration.gif 1320w, https:\/\/cdn2.hubspot.net\/hubfs\/2134380\/001-website\/images\/electrode-cleaning-illustration.gif?width=1584\u0026amp;name=electrode-cleaning-illustration.gif 1584w\" alt=\"electrode-cleaning-illustration\" width=\"528\"\u003e\u003c\/p\u003e\n\u003ch4\u003eThe HI54710-11 is supplied with Certificate of Analysis\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eProduct code\u003c\/li\u003e\n\u003cli\u003eLot number\u003c\/li\u003e\n\u003cli\u003eMean lot value\u003c\/li\u003e\n\u003cli\u003eSRMs that were used\u003c\/li\u003e\n\u003cli\u003eManufacturing date\u003c\/li\u003e\n\u003cli\u003eExpiration date\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAirtight bottles with tamper-proof seals\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eBottle is hermetically sealed to prevent any air (CO\u003csub\u003e2\u003c\/sub\u003e) from entering and causing a change in the pH buffer value.
