Programmable Humidity Controller Socket for Terrariums

If you need steady, automated climate control for a terrarium or incubator, this humidity controller and hygrostat is designed to manage both humidity and temperature across a wide range. It offers four operating modes – humidification, dehumidification, heating and cooling – and can switch temperature units between °C and °F, so you can set the precise environment your enclosure needs.

Practical control is at the core of this unit. It supports humidity from 20-95% RH and temperature settings from -10°C to 50°C (14°F to 122°F) with adjustable start/stop thresholds and an audible alarm when limits are exceeded. The device includes calibration offsets for both humidity and temperature and remembers all settings after a power cut, removing the need to reprogramme. Safety and convenience features include a 16 A, 230 V output suitable for common humidifiers, dehumidifiers and heaters, sensor error alerts, adjustable button tones, a reset function and a built-in cycle timer so you can schedule intermittent operation without extra wiring.

Use this controller where stable humidity cycles or temperature control matter most for reptiles and amphibians, such as rainforest-style vivaria, humid breeding setups or incubators. In real-world terms the 20-95% RH range covers dry to very humid conditions, while the memory and alarm functions help protect sensitive setups from sudden power or sensor issues. The plug-in design makes it a practical choice for hobbyists who want automated climate management without rewiring their setup.

Frequently Asked Questions

Is this hygrostat suitable for reptile terrariums?

Yes. It controls humidity from 20 to 95% RH and temperature from -10°C to 50°C, and can operate humidifiers, dehumidifiers or heaters without additional wiring.

Can I use this in an incubator or poultry house?

Yes. It adapts to incubators and poultry houses, provides audible alarms when limits are exceeded, and includes a smart cycle timer and automatic memory after power loss.

How do I switch between Celsius and Fahrenheit, and what control modes are available?

Press and hold SET for three seconds to toggle °C/°F. Four modes are available: humidification, dehumidification, heating and cooling, with precise start/stop thresholds.

Is this unit safe and suitable for home use with humidifiers or dehumidifiers?

Yes. Constructed from ABS, supports up to 16A/230V loads, has error indicators for sensor faults or short circuits, adjustable button tones and a reset function for safe operation.

Can I calibrate the sensor and will those settings survive a power cut?

Yes. Humidity calibration ranges from -10 to 10% RH and temperature calibration from -9.9 to 9.9°C. All settings are retained automatically after power outages.
