Digital Humidity Controller for Reptiles and Greenhouses

If unstable humidity is causing problems in a terrarium, incubator or rack, this digital humidity controller with an integrated hygrostat helps you keep conditions steady. The clear LCD readout and tactile buttons let you set humidity, temperature and hysteresis quickly so humidifiers, dehumidifiers or ventilation can be driven automatically to maintain target conditions.

The controller monitors 0 to 100% RH and 40C to 120C with sensor performance rated at +/-3C and +/-3% RH, providing dependable readings for most reptile and amphibian enclosures and incubations. It supports both humidifying and dehumidifying modes plus heating and cooling control, and the supplied 100 cm sensor cable lets you place the probe inside the habitat while the controller stays outside. In practice, using the hysteresis setting reduces rapid on-off cycling of relays and attached equipment, improving longevity and preventing short-term humidity swings. The ABS front shell and flame retardant ABS back shell suit indoor installations, and the AC110-220V 50Hz compatibility makes it suitable for a wide range of mains setups.

Key Features
