The ReptiTemp is able to control multiple heating devices and has convenient adhesive pads for mounting. Excellent for use with Zoo Med’s Ceramic Heat Emitter and the Repti Therm Under Tank Heater. Safety cover prevents accidental bumping of the temperature control dial! When used in conjunction with a timer, natural conditions are replicated by providing the proper photoperiod for your reptile, along with a beneficial nighttime temperature drop (consult a good book on your species to determine its specific temperature requirements). Range is from approximately 70° to 110°F (21° to 43°C).
