Automatic Humidity Controller for Terrariums

If you need stable humidity control for a terrarium or vivarium, this digital humidity controller and hygrostat helps automate ventilation and maintain target conditions. Designed for reptile habitats, greenhouse cabinets and propagation spaces, it includes a separate external sensor and accepts AC110-220V input for direct connection to common mains supplies.

The unit monitors a wide temperature span and the full humidity range, so it can support everything from dry setups to fully humid environments used for breeding racks or amphibian displays. A long sensor lead lets you position the probe at the actual measurement point inside the enclosure for true point readings, which is useful when you need to control ventilation or humidification based on conditions near hides, substrates or egg boxes. The large LCD and tactile buttons make settings quick to programme, while the flame-retardant rear housing offers a practical level of protection for controlled habitats.
