ReptiZoo Hygrostat HC01 | Digital Humidity Controller for Vivariums

The RZ Hygrostat HC01 is a digital humidity controller designed to maintain consistent moisture levels inside a vivarium or terrarium without requiring constant manual adjustment. Whether you're keeping species that demand high rainforest humidity or those that need a more moderate tropical environment, this unit automates the process — connecting directly to misters, foggers, dehumidifiers, or ventilation devices to keep conditions within your chosen range.

Display and Readout

A clear LCD screen shows both the current humidity reading and your programmed set-point at a glance. The HC01 operates across a humidity range of 20–90% RH, covering the needs of the vast majority of tropical and semi-tropical species kept in the UK hobby.

Adjustable Humidity Thresholds

Set both a lower and upper humidity threshold to define the acceptable range for your enclosure. The controller activates or deactivates connected devices automatically when humidity drifts outside these limits, keeping conditions stable without any manual input between checks.

Automatic Device Control

• On/Off output compatible with misting systems, ultrasonic foggers, dehumidifiers, and ventilation fans
• Activates connected devices when humidity falls or rises beyond your set thresholds
• Removes the need for manual intervention once thresholds are programmed

Why Stable Humidity Matters

Humidity that fluctuates outside a species' preferred range can contribute to dysecdysis (retained shed), respiratory infections, and fungal issues. Consistent moisture management is one of the most effective ways to support long-term animal health, particularly in closed or densely planted enclosures.

The RZ Hygrostat HC01 gives reptile keepers a straightforward, reliable tool for automating humidity control — clear to set up, easy to read daily, and practical across a wide range of vivarium setups.
