It is the most durable probe in the lineup: Red Sea's full 24-month warranty, no routine recalibration — only after cleaning — and the calibration solution is included. Salinity drift is one of the leading causes of losses in reef keeping: it is the parameter to watch first after temperature.\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 calibrates remotely over Bluetooth — you bring the probe to the sink, not the controller to the tank. Readings display continuously in ReefBeat, with alerts the moment a parameter drifts out of range.\u003c\/p\u003e\n\n\u003ch2\u003eWarranty and maintenance — the toughest in the lineup\u003c\/h2\u003e\n\u003cp\u003eUnlike the pH and ORP probes (wear items with a 6-month warranty), the salinity probe carries Red Sea's full 24-month warranty and needs no periodic recalibration. An occasional cleaning is all — and after a cleaning, you recalibrate with the included solution. One installation tip: Red Sea flags snails climbing on the sensor as the number one cause of skewed salinity readings — the manufacturer offers a snail guard (part R35853) that we can order on request.\u003c\/p\u003e\n\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the salinity probe work on its own?\u003c\/h3\u003e\n\u003cp\u003eNo — it is a sensor for the ReefControl Lite and Pro controllers. It takes one ReefSense port and its readings display in ReefBeat.\u003c\/p\u003e\n\u003ch3\u003eWhy does it cost more than the pH or ORP probe?\u003c\/h3\u003e\n\u003cp\u003eBecause it lasts: 24-month warranty versus 6, no routine recalibration versus monthly (pH), and the calibration solution is included. Over its lifespan, it is the best value of the measuring probes.\u003c\/p\u003e\n\u003ch3\u003eMy salinity reading looks wrong — is the probe defective?\u003c\/h3\u003e\n\u003cp\u003eCheck the sensor first: per Red Sea, a snail or deposit on the measuring cell is the most common cause of a skewed reading. Clean, recalibrate with the included solution, and protect the sensor.\u003c\/p\u003e\n\u003ch3\u003eDoes it transfer to another controller?\u003c\/h3\u003e\n\u003cp\u003eYes. Calibration lives in the probe, not the controller: it follows your system if you move from the Lite to the Pro.\u003c\/p\u003e\n\n\u003ch2\u003eWhy buy from ReefSolution\u003c\/h2\u003e\n\u003cp\u003eReefSolution is an authorized Red Sea dealer in Canada — no customs or exchange surprises.
