The two parts of the pH probe that cause problems are the glass sensing bulb and the reference junction.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSensing bulb\u003c\/strong\u003e\u003cbr\u003e\nThe glass bulb loses sensitivity with use and will eventually fail.

The reading is generated based on the electrical difference between the sample and reference. If the junction hole gets clogged, the pH probe will no longer function.\u003c\/p\u003e\n\n\u003cp\u003eYou can extend the life of your pH electrode in the following ways.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eStorage\u003c\/strong\u003e\u003cbr\u003e\nThe pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged.\u003c\/p\u003e\n\n\u003cp\u003eStore the pH probe in storage solution MA9015.  Only use tap water short-term if MA9015 is not immediately available and \u003cstrong\u003eNEVER store in distilled Water (DI) or Reverse Osmosis (RO) water. This will damage the sensitivity of the probe\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThis best way to store the probe is with the probe's cap filled with MA9015 Storage Solution and the cap tightened to prevent leakage. It is also recommended that to store the electrode upright to further reduce the potential for leakage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCleaning\u003c\/strong\u003e\u003cbr\u003e\nResidue from the sample can impact the sensitivity of the sensing bulb and block the junction. This is especially true if the sample has a lot of organic material. We recommend regularly soaking the probe in MA9016 Cleaning Solution for about 20 minutes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCalibration\u003c\/strong\u003e\u003cbr\u003e\nThe pH sensing bulbs become less sensitive over time so make sure that you are calibrating reguarly to keep your PRO pH controller accurate. Also, calibrate after cleaning or a long period of storage.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp class=\"fw-bold mb-0 fs-3\"\u003eSpecifications for Milwaukee MC122 PRO\u003c\/p\u003e\n\u003cdiv class=\"row\"\u003e\n   \u003ctable class=\"custom-spec-table w-100 text-center\"\u003e\n      \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eRange:\u003c\/th\u003e\n            \u003ctd\u003e0.00 to 14.00 pH\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eResolution:\u003c\/th\u003e\n            \u003ctd\u003e0.01 pH\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eAccuracy:\u003c\/th\u003e\n            \u003ctd\u003e±0.02 pH\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eSet Point:\u003c\/th\u003e\n            \u003ctd\u003e5.5 to 9.5 pH - Alarm Active when reading is higher or lower than set point\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eCalibration:\u003c\/th\u003e\n            \u003ctd\u003eManual 2 points\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eDosing Contact:\u003c\/th\u003e\n            \u003ctd\u003e1 power plug for CO2 dosing\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003epH Electrode:\u003c\/th\u003e\n            \u003ctd\u003eMA911B\/2 (included)\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eEnvironment:\u003c\/th\u003e\n            \u003ctd\u003e0 to 50°C \/ 32 to 122°F; max RH 95%\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003ePower Supply:\u003c\/th\u003e\n            \u003ctd\u003e12 VDC adapter (included)\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003ePower Drivers:\u003c\/th\u003e\n            \u003ctd\u003e115 VAC, 2A, 60Hz or 230 VAC, 1A, 50Hz\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eDimensions:\u003c\/th\u003e\n            \u003ctd\u003e5.9 x 3.2 x 1.35 inches\u003c\/td\u003e\n         \u003c\/tr\u003e\n         \u003ctr\u003e\n            \u003cth class=\"text-center fw-bold w-50\"\u003eWeight:\u003c\/th\u003e\n            \u003ctd\u003e6.3 ounces (meter only)\u003c\/td\u003e\n         \u003c\/tr\u003e\n     \u003c\/tbody\u003e\n \u003c\/table\u003e\n\u003c\/div\u003e","brand":"Milwaukee","offers":[{"title":"Default Title","offer_id":51077692653846,"sku":"MC122US","price":208.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0910\/5912\/6550\/files\/MC122US_1.webp?v=1772749272","url":"https:\/\/hydrobuilder.com\/products\/milwaukee-mc122-pro-ph-controller","provider":"Hydrobuilder","version":"1.0","type":"link"}
