Aquarium Fat Thermometer Fish Water Thermometer Floating Glass with Suction Cup White

Monitoring the water temperature in your fish tank is essential for the health of your fish, and this chubby glass thermometer makes it straightforward. It offers a temperature measurement range from 0°C to 50°C with an accuracy of ±1°C, so you can quickly check whether the water is within a safe zone. The floating design means that even if the suction cup loses grip, the thermometer stays afloat rather than sinking to the bottom. This practical feature, combined with easy-to-read numbers, helps you keep an eye on conditions without fuss. The white colouring blends naturally into most aquarium setups, and the durable glass construction is designed for long-term submersion.
