The Underwater Treasures Battery Operated Digital Thermometer features a large LCD display for easy readings, easy push-button operation, and a compact design. It displays temperature in either °C & °F, with a reading range of -10 °F to 140 °F (-23°C to 60°C). Accurate to ±1.5°F. The temperature probe is submerged in aquarium water, while the digital display (not water resistant or submersible) remains attached to your aquarium's exterior using the included suction cup.
