Replacing the sensor rather than the whole unit is the sensible fix, and because this one uses a standard BNC fitting, it works as a spare for the Bluelab ORP Meter or as a first ORP sensor for any controller that accepts one.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRemove the KCl storage cap\u003c\/strong\u003e and connect the BNC plug to your meter or controller\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKeep the electrode wet at all times\u003c\/strong\u003e - never let it dry out between uses\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibrate against a known ORP reference solution\u003c\/strong\u003e before taking a critical reading\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStore submerged in KCl storage solution\u003c\/strong\u003e in the cap provided when not in use\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for solutions of 0.2 EC and above\u003c\/strong\u003e, between -5°C and 80°C\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003cdiv class=\"hcs-specs\"\u003e\u003cul\u003e\n\u003cli\u003eSensor: platinum spiral electrode, ceramic double-junction diaphragm\u003c\/li\u003e\n\u003cli\u003eConnector: standard BNC\u003c\/li\u003e\n\u003cli\u003eCable length: 2 metres\u003c\/li\u003e\n\u003cli\u003eBody: waterproof polycarbonate, 12mm x 122mm shaft\u003c\/li\u003e\n\u003cli\u003eRange: ±2000 mV\u003c\/li\u003e\n\u003cli\u003eOperating environment: 0.2 EC and above, -5°C to 80°C\u003c\/li\u003e\n\u003cli\u003eIncludes: KCl-filled storage cap\u003c\/li\u003e\n\u003cli\u003eCompatible with: any meter or controller with a BNC ORP input, including the Bluelab ORP Meter\u003c\/li\u003e\n\u003c\/ul\u003e\u003c\/div\u003e","brand":"Bluelab","offers":[{"title":"Default Title","offer_id":53798861701386,"sku":"TLS-BLUE-013-01","price":94.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/7127\/5786\/files\/bluelab-orp-probe-1.png?v=1790169271","url":"https:\/\/hydrocropshop.co.uk\/products\/bluelab-orp-probe","provider":"Hydro Crop Shop","version":"1.0","type":"link"}
