<b> Monitor Your Pet’s Environment </b><br> An appropriate Environmental Temperature Range (ETR) within your pet's enclosure not only gives them more energy and makes them more active, but it also guards them from contracting any possible ailment. Different species of animals have their own ideal living conditions. While some prefer a more dry or cold climate, others may need to live in a hot and humid habitat. As a dutiful pet owner, it is highly recommended that you add the SunGrow Dual Thermo-Hygro Meter in order to precisely monitor both the temperature and humidity levels in their enclosures. Maintaining a proper environment means that your living creatures are far less likely to get stressed and are far more likely to thrive and live long happy lives. <br><br> <b>How To Read the Gauges</b> <br> Dependable and long-lasting, the 3” x 0.9” SunGrow Hermit Crab Habitat Humidity & Temperature Meter is large enough that it is easy to read but small enough to not distract from your pet’s native habitat. Brightly colored sections make it easy to get a general reading from a distance, while thick and thin black lines and detailed labeling provide an accurate measurement up close. The temperature is measured in Fahrenheit and has a range of 0℉ to 120℉. Below 60℉ is colored blue and above 80℉ is colored red, so that the remaining green section signifies the perfect hermit crab temperature range of 60℉ to 80℉. The hygrometer gauge measures the moisture content from 0% to 100%. Moisture level under 40% is coded in blue, above 70% is coded red, leaving a green comfort zone in the middle of 40% - 70%. <br><br> <b>Where to Place the Measuring Unit</b> <br> To get the most accurate readings of the temperature and moisture content, here are a few helpful hints and recommendations. <br> If your pet’s habitat is small to medium-sized, you will want to place the SunGrow Thermometer/Hygrometer Combo Unit inside and on the floor of your tank.<br>
