The Klein Tools IR5 Dual Laser Infrared Thermometer, -22° to 752°F is a professional dual-laser targeting infrared thermometer that offers a wide measurement range, a tight distance-to-spot ratio, and several calculation modes to facilitate different temperature measurement applications. Dual lasers assist in targeting the measurement area. The distance between the two laser spots on the surface of the object being measured approximates the diameter of the circular measurement area from which the infrared sensor is collecting data.
