Rechargeable Digital Aquarium Thermometer

Stay on top of your aquatic pets’ health with the TJY-001 Digital Aquarium Thermometer from Extension Instruments — the hassle-free, accurate way to monitor water temperature in your fish tank. ✅ External Stick-On Design, No Water Contact Required Unlike submersible thermometers that risk leaks or contamination, this compact thermometer adheres directly to the outside of your aquarium glass (below the waterline) using strong 3M adhesive. It keeps your tank clean and maintenance-free while delivering reliable readings through the glass. ✅ Fast, Accurate Temperature Monitoring Featuring a precision sensor, the thermometer updates readings every 3 minutes, ensuring you always have the latest water temperature data. With a wide measurement range of 0°C to 60°C (32°F to 140°F) and a clear LED display (available in blue or green backlight), you can easily read temperatures from across the room in Celsius (°C). ✅ Ultra-Low Power Consumption & Simple Operation Designed for efficiency, the thermometer enters a low-power sleep mode (current draw <3µA) after 5 seconds of display use, extending battery life significantly. Just tap the power button to wake it up and view the current temperature — no complicated setup required. ✅ Versatile for All Aquarium Types Perfect for freshwater tanks, saltwater tanks, planted aquariums, shrimp tanks, and even small terrariums, this thermometer works with any glass aquarium. Its compact size (43 x 43 x 12 mm / 1.69 x 1.69 x 0.47 in) and lightweight design (16g / 0.56 oz) make it easy to hide or place anywhere on your tank. ✅ Built for Aquarists, by Aquarists You’re not just buying a thermometer — you’re investing in the health and comfort of your fish, shrimp, and aquatic plants.
