Red Sea ReefSense ORP Probe

Gain real insight into your water quality with the Red Sea ReefSense ORP Probe. ORP (Oxidation-Reduction Potential) is a key indicator of how clean and healthy your water is, and a stable, high ORP means a low-waste, well-oxygenated system. This fully digital probe delivers continuous, interference-free readings to the Red Sea ReefBeat app through a ReefControl controller, and paired with ReefControl Power it can even safely automate an ozonizer.

Why You’ll Love It

• 24/7 ORP monitoring, track your redox potential in real time for a clear picture of water cleanliness.
• Double-junction design with dual ceramic external junctions for increased longevity.
• Precise, accurate to 30 mV with 1 mV resolution.
• Fully digital, immune to the electromagnetic interference from pumps and lights that causes false readings on analog probes.
• Ozonizer-ready, safely automate an ozonizer when paired with ReefControl Power.

Specifications

Complete Your Setup

• Connect it to a ReefControl Pro or ReefControl Lite controller, or the ReefControl Pro Deluxe Kit.
• Mount it with a Single Probe Holder or the Magnetic 4-Probe Holder.
• Add more parameters with the Temperature Probe and expand ports with the 4-Port Expander, or browse more reef gear.

FAQ

What does ORP tell me?
It measures your water’s oxidation-reduction potential in millivolts, a real-time gauge of how clean and well-oxygenated the water is.

Why digital instead of analog?
The reading is processed inside the probe, so it is immune to the electrical interference from pumps and lights that causes analog probes to give false readings.

Can it run an ozonizer?
Yes. With a ReefControl controller and ReefControl Power, it can switch an ozonizer automatically based on your target ORP.
