It detects the alkalinity and acidity of the pool water and reports it back to the controller.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat it does\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA chemical controller is only as good as the probes feeding it. The pH sensor is the input the controller uses to decide when to add acid or base, so once the probe starts to drift the controller keeps dosing confidently on numbers that are no longer true. That shows up as pH that swings wide between service visits, or a controller reading that no longer agrees with a hand test.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting and service life\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis is the genuine Pentair sensor for these two controllers, made for direct installation in place of the existing probe. Probes are consumable by nature: cleaning and recalibration buy time, but a sensor that will not hold calibration is due for replacement.\u003c\/p\u003e","brand":"Acutrol","offers":[{"title":"Default Title","offer_id":48628865663188,"sku":"ATR-451-4125","price":367.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_38c17aee-b3f8-4acd-a771-3f5e0484caf3.jpg?v=1788756745","url":"https:\/\/www.activepoolsupply.com\/products\/pentair-744000260-ph-sensor-for-ak110-and-ak600-chemical-controllers","provider":"Active Pool Supply","version":"1.0","type":"link"}
