When the sensor degrades or drifts out of calibration range, pH dosing accuracy is compromised — resulting in under- or over-treatment of the water. Replacing the sensor with the correct OEM part restores accurate chemical feed control. Match the part number on your existing sensor or your IntelliChem® documentation before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 20px 0; border: 1px solid #ccc;\"\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003ePentair Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e522186Z\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eAlso Known As\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e522186\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f8f9fa;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eApplication\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003ePentair IntelliChem® Chemical Controller\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eQuantity Included\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePro Tip\u003c\/h3\u003e\n\u003cp\u003epH sensors have a finite service life — typically one to two years depending on water conditions and usage frequency. If your IntelliChem® controller is reading pH erratically or consistently off from a manual test, calibrate the sensor first using the controller's calibration procedure. If accurate calibration cannot be achieved, sensor replacement is the correct next step. Keep the sensor port free of scale buildup during routine equipment maintenance to extend service intervals.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual: --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53962258415891,"sku":"522186Z","price":144.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-ph-sensor-for-intellichem-chemical-controller-522186.webp?v=1774968784","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_522186z","provider":"Poolaroo","version":"1.0","type":"link"}
