How far away does the TempGun shoot?
All of the non-contact TempGuns on the market use Infrared technology to get a reflected surface temperature from the desired object. The infrared beam “shoots out” in a cone shape, narrowest right at the sensor of the TempGun, meaning the farther away you are, the wider the area you are temping out. So the usable distance of a TempGun is largely dependent on the object you are shooting. If you want to shoot engine head temps in an RC Car, you are trying to shoot an area about a quarter of an inch in diameter, right in at the glow plug. For such a tight reading, you want to be as close as possible. If you are shooting the tire temps on a Stock Car, you have a much larger area, and you can be further away. For road or track temperatures, you can shoot from a few feet away and get an accurate reading. Remember, the closer you are to your object, the smaller the area that you will be reading. For our use in reptile breeding at Pro Exotics , I typically shoot cages and animals from 8-12 in
