The IRK Infrared Thermometer has been a favorite professional tool for broad range temperature measurements among industry and home use. Our new IRK-2 includes all the great features of the IRK now with new circle laser IR targeting, larger LCD display, and higher temperature range.

  • The IRK-2 Infrared Thermometer is equipped with a circle laser indicator, which allows you to better approximate your target area without the guesswork of a single laser. The 8 laser dots show you the diameter of the area being measured. As you move closer or further from the target the laser circle will change diameter. This infrared thermometer has an adjustable emissivity feature, which allows you to measure a variety of surface types. For poorly lit areas, the infrared thermometer's backlit display can be toggled on (or off) for easy reading of surface temperatures.

    The IRK-2 Infrared Thermometer includes a thermocouple socket for use with any type K thermocouple probe. A two line display shows infrared and thermocouple measurements simultaneously. And, with a 12:1 distance-to-spot ratio, the Industrial Infrared Thermometer allows you to measure small target areas from further away (1 inch spot at 12 inch distance). This keeps the lens cool when measuring hot surface temperatures.

    The IRK-2 Infrared Thermometer's display features include Min/Max, Diff. Mode, Avg. Mode, Hi/Low alarms, and continuous scan mode with a large main temperature display, which reads in °F or °C. It's everything you need in a professional infrared thermometer.

    *Accuracy can be affected by the emissivity setting, target spot size, and rapid changes in ambient temperature.

    **EMC/RFI:Readings may be affected if the unit is operated within radio frequency electromagnetic field strength of approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.
