Replacing a worn or drifting probe restores accurate pH measurement and keeps automated chemical dosing on target.\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\u003eHayward Part Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003eGLX-PROBE-PH\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #ffffff;\"\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e\u003cstrong\u003eUPC\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #ccc; padding: 10px;\"\u003e761418009916\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003ePoolaroo Pro Tip\u003c\/h3\u003e\n\u003cp\u003epH probes are consumable sensors with a finite service life. Even if the probe reads within range, calibrate it against a reliable test kit reading at the start of each season and again mid-season. A probe that requires increasingly large calibration offsets over time is nearing the end of its useful life and should be replaced promptly — an out-of-calibration pH probe will cause your Sense and Dispense system to dose incorrectly, affecting both water chemistry balance and sanitizer effectiveness.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-06-18 --\u003e","brand":"Hayward","offers":[{"title":"Default Title","offer_id":54303481135379,"sku":"GLX-PROBE-PH","price":477.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/HPPGLXPROBEPH_0.jpg?v=1781650416","url":"https:\/\/poolaroo.com\/products\/hayward_glx-probe-ph","provider":"Poolaroo","version":"1.0","type":"link"}
