Klein Tools IR5 is a professional dual-laser targeting infrared thermometer, offering a wide measurement range, a tight 12:1 distance-to-spot ratio, dual targeting lasers, and several calculation modes to facilitate different temperature measurement applications. The 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 diamater of the circular measurement area from which the infrared sensor is collecting data.
