- QUICK TEMPERATURE RECOGNITION: Our round aquarium thermometers display the water temperature at a glance. Instantly readable readings help you assess the feeding environment and habitat conditions without complex steps. - EASY INSTALLATION: Peel off the backing and attach to the outside of the aquarium or other smooth surfaces. No tools required. The special adhesive backing provides secure, long-lasting use while keeping the viewing area unobstructed. - BEAUTIFUL AND PRACTICAL: The round design adds a touch of style to your tank setup. It complements fish and turtle enclosures while delivering essential temperature information. - HIGHLY SENSITIVE AND CLEAR: A temperature-sensitive color bar with easy-to-read color markings shows the current temperature for simple monitoring and averaging. This makes it a reliable tool for ongoing tank management. - USE SCENARIOS: - In freshwater or marine aquariums, monitor and maintain the target temperature to support fish health and stable feeding behavior. - In turtle tanks or terrariums, place the thermometer on the outside of the enclosure to track habitat temperature without disturbing inhabitants. - During seasonal changes or quarantine setups, quickly verify temperature during water changes, acclimation, or habitat adjustments.
