{"product_id":"red-sea-reefsense-orp","title":"Red Sea ReefSense ORP — Digital Redox Probe for ReefControl Controllers with Bluetooth","description":"\u003cp\u003eThe \u003cstrong\u003eRed Sea ReefSense ORP probe\u003c\/strong\u003e measures the water's oxidation-reduction potential (redox) — a global indicator of the tank's capacity to break down waste — plugged into a ReefControl controller. It is the probe for advanced reefers: those running ozone, or who want to see a background problem coming before it shows in tests. Know before you buy: periodic validation requires a 460 mV solution sold separately, and like every ORP electrode it is a wear item — about a 12-month lifespan, 6-month warranty.\u003c\/p\u003e\n\n\u003cdiv style=\"margin:20px 0;\"\u003e\u003cvideo controls preload=\"metadata\" playsinline poster=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0513\/7108\/1899\/files\/preview_images\/1338385c9a05467fba4fb82e4d8d2725.thumbnail.0000000000.jpg?v=1786662047\" data-vs=\"rc-family-en\" style=\"width:100%;border-radius:8px;\"\u003e\u003csource src=\"https:\/\/cdn.shopify.com\/videos\/c\/vp\/1338385c9a05467fba4fb82e4d8d2725\/1338385c9a05467fba4fb82e4d8d2725.HD-1080p-2.5Mbps-91555257.mp4\" type=\"video\/mp4\"\u003e\u003c\/video\u003e\u003c\/div\u003e\n\n\u003ch2\u003eWhat makes ReefSense probes different\u003c\/h2\u003e\n\u003cp\u003ePer Red Sea's official manuals, every ReefSense probe is digital and stores its calibration in onboard memory: it plugs into any port of a \u003ca href=\"\/en\/products\/red-sea-reefcontrol-lite\"\u003eReefControl Lite\u003c\/a\u003e or \u003ca href=\"\/en\/products\/red-sea-reefcontrol-pro\"\u003ePro\u003c\/a\u003e, moves between controllers without recalibrating, and validates over Bluetooth at the sink.

Like the pH probe, the ORP electrode is a wear item: about 12 months of continuous use, 6-month warranty. A reading that no longer reacts to changes in the tank is the classic end-of-life sign.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the ORP probe work on its own?\u003c\/h3\u003e\n\u003cp\u003eNo — it is a sensor for the ReefControl Lite and Pro controllers.
