Red Sea ReefATO+ Replacement Sensor — Titanium Level and Temperature Probes R35622

This is the genuine replacement sensor (part R35622, V2) for the Red Sea ReefATO+ 3-in-1 auto top off system. It is not the full system — it is the part you swap in if your sensor is damaged or worn out.

What this sensor includes

• Multi-input titanium probes with EC (solid-state) technology: they detect whether the water level is above, below or at the target point, with no float and no moving parts.
• Built-in digital thermometer, pre-calibrated to 0.1° according to Red Sea — replacing the sensor also renews the temperature probe of your system.
• Slim profile designed for the ReefATO+ magnetic mount (glass up to 12 mm).

Saltwater aquariums only

Like the full system, this EC sensor requires the electrical conductivity of seawater to operate. It is not suitable for freshwater.

Does this sensor work in freshwater?

No. Red Sea states the sensor's EC technology requires the conductivity typical of seawater: this is a saltwater-only part.
