BOYU BT-10 | Digital Thermometer
The BOYU BT-10 is a compact, 100% waterproof submersible digital thermometer explicitly designed for real-time temperature tracking inside freshwater and saltwater aquariums.
Unlike standard external stick-on or wired sensor units, this model features a completely wireless design with an integrated probe, meaning the entire unit safely sits underwater inside your fish tank to provide clear LCD readings.
Key Features
- Submersible & Clutter-Free: Operates fully underwater. It eliminates messy hanging wires outside the aquarium glass.
- Dual Environment Use: Built with non-corrosive sealing. It works efficiently in both freshwater and marine/reef tanks.
- High Readability: Equipped with a clear digital LCD screen that displays immediate, precise temperature readouts.
- Leakproof Seal: Features a heavily sealed plastic housing that isolates the battery slot and electrical components from water leakage.
- Suction Cup Attachment: Includes a heavy-duty suction cup to easily press and lock the thermometer onto any internal glass surface.
Installation Instructions
- Twist open the secure back cover. Insert the provided butto cell battery.
- Thread the battery cover back into place and twist it tightly to ensure the waterproof seal is fully locked.
- Select an area inside your tank (ideally away from direct heater currents for the most accurate average reading).
- Firmly press the suction cup onto clean aquarium glass to lock it into place.
