Description
Product Overview
The Exo Terra Thermostat for Terrariums is a precision environmental control unit designed specifically for reptile and amphibian habitats. Engineered by Rolf C. Hagen (USA) Corp., this model PT2464 measures 10 x 10 x 2 inches and weighs just 2.16 pounds, making it compact enough to fit discreetly on any terrarium setup. The device offers a wide temperature range from 10 °C to 60 °C (50 °F – 140 °F) and can maintain humidity levels up to 99 % RH, providing the exact conditions required for species that demand strict climate regulation. Its dimming function allows users to adjust heating and humidifying output with fine granularity, supporting devices up to 600 W such as heat mats, heat cables, ceramic heaters, and heat bulbs. The intuitive blue LCD displays current temperature and humidity, while a red LED and heating symbol indicate when the heating element is active, and a blue LED signals humidifier operation. This combination of features ensures reliable, real‑time monitoring and effortless adjustments, reducing the risk of temperature spikes or humidity drops that could stress or harm delicate pets.

Usage
Designed for both hobbyists and professional breeders, the thermostat excels in a variety of terrarium environments, from small desktop vivariums to large, multi‑section habitats. Whether you are housing tropical snakes, desert lizards, or aquatic amphibians, the unit’s dual control capability lets you set separate daytime and nighttime temperature and humidity setpoints, mirroring natural day‑night cycles. The dimming feature is especially valuable for species that require gradual temperature changes, such as chameleons that thrive on subtle thermal gradients. Users can connect the thermostat to a range of heating devices, including under‑tank heat mats for reptiles that need bottom heat, overhead heat bulbs for basking zones, and ceramic heaters for precise spot heating. The humidity control works equally well with misting systems, foggers, or ultrasonic humidifiers, ensuring a consistent moisture level that supports skin shedding and respiratory health. Its robust construction and reliable performance make it suitable for long‑term use in research facilities, zoos, and educational settings where accurate climate control is essential.
