Installation Instructions for Humidity GaugeLocate and clean a small, smooth area inside and near the center of the habitat. Make sure the location is easy to view from the outside. Avoid placing the humidity gauge directly near extremely warm or wet areas. Remove the adhesive backing from the back of the humidity gauge and press firmly in the chosen location. The natural habitats for your pets provide great clues to their humidity needs. Desert animals require very low humidity and tropical animals require very high humidity. Frequent misting and available water supply, open to the habitat help maintain a tropical environment. Good ventilation and smaller, enclosed water supply will help maintain a drier desert-like environment.
