Submersible USB Aquarium Thermometer

This digital thermometer is built for glass aquariums and suits both freshwater and saltwater setups. It provides continuous water-temperature monitoring for fish, turtles and other aquatic life. The unit runs on 5 V power supplied through a 6.56 ft USB cable.

Build integration and placement

The probe sits directly in the water for responsive readings while the display stays outside the tank. Three strong suction cups secure the compact 1.96 × 1.96 × 0.98 inch body wherever you need it. A 24-hour always-on mode and a custom timer mode let you control screen visibility without extra wiring.

Calibration, timer and brightness

An on-board calibration function lets you fine-tune readings within the 32 °F to 122 °F range for tighter accuracy. Adjustable screen brightness and the one-touch timer switch adapt the display to day or night viewing. No batteries are required because the device draws power from the USB connection.

Questions about this item

How long can the display stay on continuously before it needs a break?

The unit offers a 24/7 Always-On mode so the screen can run non-stop without a duty-cycle limit.

Does the probe or cable get warm during all-day operation?

It runs on an ultra-low 5 V supply and the fully potted circuit board stays cool, so neither the probe nor the 6.56 ft USB cable produces noticeable heat.

What power source must I already have to run this thermometer?

A standard USB port or USB mains adapter supplying 5 V is required; the thermometer does not operate on batteries.
