Replaceable CR2032 Battery & Detachable Design:Powered by a CR2032 battery with up to 1 year service life. Thanks to the card-slot structure, the thermometer can be quickly removed and reinstalled without tearing off the adhesive.
Precise Temperature Reading:Temperature measuring range: 32–140°F. Provides reliable readings with an error range of ±0.9°F, helping you keep a stable living environment for your aquatic pets.
Simple External Installation:Stick the thermometer on the outer glass of your fish tank below the water line using the included adhesive. Allow 5 minutes for stabilization to get accurate internal water temperature readings.
Convenient Touch Wake-Up Display:Simply tap the unit to activate the LED screen. The display will automatically turn off after 10 seconds to save battery power.
Important Notice: This thermometer is NOT waterproof; only use it outside the aquarium glass. Once adhered firmly, it is hard to reposition. One extra spare adhesive pad is included for your future use.
