Intended for a broad variety of applications, the IRK gives you two instruments for the price of only one. We make a huge selection of quality type K thermocouples to make the IRK a perfect fit for nearly any purpose. Select a type K probe from our probe page.
Most infrared meters sold for less than $100 have the emissivity value fixed at the factory for 0.95. That makes them useful for many organic materials but renders them inaccurate when used with any other material. The emissivity setting of the IRK adjusts in 0.01 increments from 0.1 to 1.0. Here's the neat part: if you don't know the emissivity of your material, simply use a contact thermocouple to measure the surface temp, then adjust the IRK's emissivity value till your infrared reading matches the thermocouple reading. Slick, huh?
You also get Min, Max, Hold, Diff, Avg, Hi Alarm, Lo Alarm, a bright laser, diplay backlight and a °C/°F button. Even with all this, the IRK is so easy to use. Just press the mode key once-each to step through these features. You probably won't even read the manual.
If you want one meter for everything, get this. Pick some probes and you're ready!
