Pro Exotics Temp Guns are terrific tools to give immediate and accurate non-contact surface temperatures.

Sighting laser, non-contact and infrared technology.

The PE-2 unit adds a much requested red sighting laser, and an expanded
temperature range to 482F (easily switchable to 250C). The PE-2 has an
adjustable emissivity setting for precise calibration, and perhaps best
of all, a tight infrared "cone" distance to spot ratio (D:S) of 8:1. That
means at a distance of 8 inches, you are reading an area just 1 inch
in diameter. At a distance of 2 feet, an area of just 3 inches
