• This glass aquarium thermometer provides a clear view of water temperature through a red liquid column and printed Celsius and Fahrenheit scales. The suction cup holds it against the inside wall of the aquarium for convenient temperature checks.
• Measuring 11 cm long and 1.3 cm in diameter, it has a measuring range of 0–40°C and an accuracy of ±1°C. Its floating design allows it to stay afloat if it becomes detached from the tank wall.
