Because the electrode wears with use, expect roughly 12 months of continuous service before it needs replacing. The classic end-of-life sign is a reading that stops reacting to real changes in the tank — if that happens, the probe needs replacing rather than recalibrating.\u003c\/p\u003e\n\u003ch3\u003eGoes well with\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefControl Lite or Pro\u003c\/strong\u003e — the controller this probe requires to operate.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefSense pH \u0026amp; Temp Probe\u003c\/strong\u003e and \u003cstrong\u003eReefSense Salinity \u0026amp; Temperature Probe\u003c\/strong\u003e — build out a fuller picture of water chemistry on the same controller.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefSense Magnetic 4-Probe Holder\u003c\/strong\u003e — mounts this probe alongside up to three others at a consistent depth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReefControl Power\u003c\/strong\u003e — lets an ORP reading drive automations such as ozoniser control.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty and delivery\u003c\/h3\u003e\n\u003cp\u003eRed Sea covers the ORP probe for 6 months as a wear item, shorter than the 24-month warranty on non-wearing ReefSense accessories, in addition to your rights under Australian Consumer Law.
