Infrared temperature guns are an invaluable tool when setting up your enclosure to measure the surface temperatures of everything. We use these almost daily to check on animals and enclosures in the summer and winter months to make sure everything is within acceptable ranges. Simply hold the gun near the surface you're measuring, press the button, and within 1 second you have an accurate measurement of the temperature.
Temperature measure ranges from -27 up to 430 degrees F.
