Stick-On Digital Aquarium Thermometer (°C & °F)

Accurate, touch-activated temperature monitoring for any aquarium

This stick-on digital fish tank thermometer offers clear, reliable temperature readings without cluttering your aquarium with probes or cables. Constructed from durable ABS and powered by a built-in 3V lithium manganese battery, it delivers consistent performance in both home and professional aquarium setups.

Installation is straightforward: simply peel off the adhesive backing and press the thermometer onto the outside glass of your tank. A light touch on the display activates the screen, which remains illuminated for easy reading before automatically returning to sleep mode after approximately 5 seconds to conserve energy. The wide 160° viewing angle and high color saturation ensure that readings remain clear from multiple positions and in varying light conditions.

With a measuring range of 0-60°C (0-140°F), this thermometer is suitable for freshwater, saltwater, marine, and tap water aquariums. An external, highly accurate sensor reads the water temperature through the glass, eliminating the need to submerge the device and helping maintain a clean, safe environment for your fish and aquatic plants. The integrated low-power battery is designed to last for up to five years under normal use.
