The Digital Aquarium Thermometer with Transparent Large LCD Display offers a clean, cordless, and highly accurate way to monitor your tank’s temperature. Featuring a backside temperature sensor, this thermometer attaches to the outside of your aquarium or terrarium—keeping electronics safely out of the water while still providing precise readings.

Designed for reliability, it delivers accurate temperature readings within ±1°C / ±2°F, ensuring a stable and healthy environment for your aquatic or terrarium pets.

Easy to install and simple to use—just place the battery, stick it below the waterline on the outside of the tank, and long-press the buttons to switch between °C and °F. Ideal for freshwater, saltwater, reef, planted tanks, turtle tanks, terrariums, reptile enclosures, beer brewing, wine barrels, and more.
