The ThermoHAWK™ Series touchless, pen-sized and handheld gun thermometers allow you to instantly check the surface temperature of almost any object. The ThermoHAWK™ units contain a patent-pending thermopile sensor on a chip technology which provides unique advantages over the older pyrometer infrared sensors. This breakthrough technology is what allows the ThermoHAWK™ to be incredibly compact in size and does not require the units to be calibrated for years.
