Digital Dual-Scale Tank Thermometer

A slim-line LED thermometer designed specifically for glass-walled aquariums and terrariums. Measures 9.5 cm in height, 2.5 cm wide, and just 1.2 cm deep; weighs only 28 grams. Constructed from clear, shatter-resistant acrylic with an integrated LED display. Operates on one CR2032 button cell (supplied), rated for up to 12 months of continuous use. Delivers stable, repeatable readings across typical hobbyist temperature ranges (0–50°C / 32–122°F) with no warm-up delay. Suitable for freshwater, marine, paludarium, and arid or tropical terrarium applications where ambient and water-surface temperature correlation matters.
