ReefSense ORP Probe - Red Sea

The ReefSense Digital ORP Probe gives you a clear view of your aquarium’s water quality by continuously measuring Oxidation Reduction Potential (ORP). When connected to a ReefControl Lite or ReefControl Pro, it provides real-time readings, notifications, and detailed logs through the ReefBeat app.

In combination with ReefControl Power, this probe becomes the cornerstone of safe ozone control. It can be used to automate an ozonizer or other DC and AC equipment based on live ORP values, helping you maintain clean, clear water without risking overdosing.

The probe features a durable double junction design with dual ceramic external junctions for extended life in harsh saltwater environments. It is accurate to 30 mV with a precision of 1 mV.

Detailed Description

ORP is one of the best indicators of how effectively your system is breaking down waste and maintaining water clarity. Higher, stable ORP readings generally point to cleaner water and a healthier environment for fish and corals.

The ReefSense Digital ORP Probe is designed specifically for this role within the ReefControl ecosystem. Because it is fully digital, it converts its readings inside the probe before sending them to the controller. This design makes it resistant to electromagnetic interference from pumps, lights, and other gear that can cause analog probes to drift or misread.

The double junction, dual ceramic construction provides added protection against contamination and extends probe life. This makes it well suited for continuous use in marine systems where stability and accuracy matter.

Once connected to a ReefControl Lite or Pro, the probe delivers live ORP values, historical logs, and alert capability via the ReefBeat app. When used with a ReefControl Power module, you can automate an ozonizer based on your chosen ORP range. Set your target level, and the system will switch the ozonizer on or off as needed to maintain that range. This approach is the safest way to run ozone and helps prevent overdosing while keeping water polished and clear.

Calibration is simple and stored directly on the probe. You can move it between ports or even different controllers without having to recalibrate. For added convenience, you can also use it via Bluetooth for remote calibration at a sink.

Key Features

Continuous ORP monitoring
Provides live, 24/7 ORP readings in millivolts (mV) to track water cleanliness and oxidation capacity.

Ideal for ozone control
Enables safe, automated control of an ozonizer by maintaining a user-defined ORP range.

High precision and accuracy

• Accuracy: 30 mV

• Precision: 1 mV

Digital, interference-resistant design
Internal digital conversion prevents electromagnetic interference from pumps, lights, and other equipment from affecting readings.

Durable double junction sensor
Uses dual ceramic external junctions for increased longevity and stable performance in saltwater conditions.

ReefBeat integration
Connects to any available port on a ReefControl Lite or Pro for live monitoring, data logging, and mobile notifications.

Smart calibration storage
Calibration data is saved on the probe itself, so it can be moved between ports or controllers without re-calibrating.

Remote Bluetooth use
Can be connected via Bluetooth for convenient calibration away from the tank.

Automation Possibilities

Ozonizer automation
With ReefControl Power, automatically switch your ozonizer on or off to maintain a stable ORP range for optimal water clarity.

Water quality alerts
Receive instant notifications if ORP drops sharply, signaling a potential issue like overfeeding or a dead fish, or if it rises too high.
