Zilla 11517 Humidity and Temperature Dial Gauge
An ideal choice for entry-level terrarium owners who want to monitor humidity and temperature, the two critical factors in reptile activity, disease resistance and breeding success. Traditional needle gauges display relative humidity from 0-100%, temperatures in a range from 60°-120°F (16°-49°C). The bright, easy-to-read dial mounts in seconds on the back wall of any terrarium, using the enclosed permanent double-sided tape or an included suction cup that can be removed for easy tank cleaning.
