Wireless convenience: This digital aquarium thermometer operates without cords. Attach it to the outside of your aquarium below the waterline for a tidy setup that keeps sensors out of the water while providing essential temperature monitoring. Precise temperature monitoring: Measures 0 to 60 C (32 to 140 F) with an accuracy of +/- 1 C. Reliable readings help maintain optimal conditions for your aquatic pets and reduce stress-related issues. Clear LED display: Bright LED screen shows current temperature clearly and can be read from across the room without disturbing the tank environment. Easy installation: Peel off the self-adhesive backing and attach the thermometer to the exterior of the tank. No complicated setup or ongoing maintenance, suitable for both beginners and experienced hobbyists. Use scenarios: - Freshwater community or tropical tanks where stable temperature supports fish and invertebrates. - Breeding or sensitive species tanks that require tight temperature control. - Quarantine or hospital tanks where unobtrusive, quick temperature checks are important.
