The Exo Terra Infrared Thermometer is a pocket sized, light-weight “point-and-click” thermometer that instantly measures the temperature of a surface or object. Point the Exo Terra Infrared Thermometer towards any desired object and with a click on the button the temperature will be shown on the large, easy-to-read digital display. The Infrared Thermometer can be used to determine the temperature of basking sites, hiding caves and shelters, hibernation temperatures, incubation media, your reptile’s body temperature, or to measure temperatures “on-the-spot” during field trips. To determine temperature gradients, the Infrared Thermometer will measure the ambient temperature as long as you press and hold the button, once you release the button the last measured temperature will be displayed. A small LED targeting light assists you to measure the correct spot and shows the diameter of the measured surface. It also allows you to scan difficult-to-measure spots with low light conditions, like inside hiding caves, behind branches, underneath leaves, etc.
