The clear glass thermometer displays temperatures in both Celsius and Fahrenheit for international use. The thermometer is suitable for use in freshwater or saltwater tanks.

The glass thermometer can be cleaned as needed and the smooth glass surface resists fogging and algae growth. Underwater Treasures Floating Glass Thermometers require no batteries or special equipment to operate and are guaranteed to be accurate.
