I.R.K.
Infrared + Type K TC input
- High Quality 11:1 optics
- Read up to 1999°F with an optional thermocouple
- Industrial applications, food processing, food service
- Adjustable emissivity for multiple surface materials
- Endless variety of Type K probes are available
- For a limited time, purchase an I.R.K. meter and get a free #303-159 Fast Response probe!
Intended for a broad variety of applications, the I.R.K. gives you two instruments for the price of only one. We make a huge selection of quality type K thermocouples to make the I.R.K. 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 I.R.K. 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 I.R.K.’s emissivity value till your infrared reading matches the thermocouple reading. Slick, huh?
You also get Max, Min, Hold, Diff, Avg, Hi Alarm, Lo Alarm, a bright laser, diplay backlight and a °C/°F button. Even with all this, the I.R.K. 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!
