Wireless Design: The aquarium thermometer features a wireless design that helps prevent fish from accidentally ingesting it. Unlike probe-style thermometers, this digital aquarium thermometer only requires removing the adhesive film before placing it outside the aquarium for accurate temperature readings. The wireless setup contributes to a cleaner and safer environment for aquatic life. Precise Measurement: Equipped with a high-precision temperature sensor, the thermometer updates readings every 5 seconds and quickly detects temperature changes. It measures temperatures from 0 to 99.9°C with a resolution of 0.1°C and a maximum deviation of ±0.5°C, ensuring reliable and accurate monitoring for your aquarium. Efficient Energy Use: A simple touch activates the display, and after 5 seconds of inactivity, the thermometer automatically enters sleep mode to conserve power. It is powered by a built-in CR2032 coin cell battery that can last up to 24 months. Battery replacement is straightforward when needed. Wide Application: Suitable for various water types, including freshwater, saltwater, seawater, and tap water. This digital aquarium thermometer effectively monitors temperature in different environments such as fish tanks, turtle enclosures, coral tanks, and plant pools, helping maintain an optimal and comfortable water temperature for aquatic pets.
