HYDROS Slim Temperature Sensor | Waterproof Aquarium Temperature Probe

Monitor Your Aquarium's Temperature with Confidence

The HYDROS Slim Temperature Sensor is a compact, waterproof temperature probe designed to provide accurate, reliable temperature monitoring for your HYDROS Aquarium Control System. Whether you're managing a reef aquarium, freshwater tank, or all-in-one setup, maintaining a stable water temperature is essential for the health of your fish, corals, and invertebrates.

Featuring a slim IP68-rated waterproof design, a generous 79-inch cable, and a secure GX12 aviation-style connector, this sensor connects directly to any compatible HYDROS Sense Port for plug-and-play operation—no additional power supply required.

Please Note: A compatible HYDROS Controller (such as the Control 2, Control 4, or other compatible HYDROS controller) is required for operation and is sold separately.

Key Features

• Accurate and dependable aquarium temperature monitoring

• Slim waterproof IP68 design for discreet installation

• Long 79" cable for flexible placement

• Secure GX12 aviation-style connector

• No moving parts for long-term reliability

• Plug-and-play installation with any HYDROS Sense Port

Designed for Tight Spaces

Measuring only 1.6 inches long and 0.32 inches in diameter, the HYDROS Slim Temperature Sensor easily fits inside:

• All-in-one aquarium rear chambers

• Aquarium overflows

• Sumps

• Filter compartments

• Hidden equipment areas

Its compact size allows you to monitor water temperature without distracting from the appearance of your aquarium.

Smarter Temperature Monitoring

When paired with a compatible HYDROS Controller, the Slim Temperature Sensor does much more than display your water temperature.

Using the HYDROS app, you can:

• Receive mobile alerts if water temperatures move outside your safe range

• Automate heaters, chillers, or cooling fans

• Create custom temperature safety limits

• Monitor your aquarium remotely

For example, you can configure HYDROS to notify you if your aquarium rises above 82°F or falls below 78°F, helping protect your livestock before temperature swings become dangerous.

Automation functions require compatible HYDROS power accessories, such as the HYDROS Power 4 or HYDROS Smart Plug.

Why Use Multiple Temperature Sensors?

For larger systems or aquariums with remote sumps, multiple temperature sensors provide additional peace of mind.

Common installations include:

• One sensor in the display aquarium

• One sensor in the sump

• Additional sensors for redundancy and equipment verification

Monitoring multiple locations helps identify temperature differences throughout your system and adds an extra layer of protection.
