InfraPro Infrared Thermometers from Oakton Instruments

InfraPro Infrared Thermometers have a wide variety of advanced features for your exact application!


Laser sighting pinpoints exact target
Select from fixed or adjustable emissivity—adjustable emissivity lets you measure a variety of surfaces more accurately
Backlit display for easy reading even in the dark
Automatically display maximum reading
Hold function freezes reading
°C/°F selectable



Infrared thermometers with just the features you need for your exact application! Use noncontact infrared temperature measurement for areas that are difficult to reach or too hot to touch, to avoid contamination, to measure moving objects, and much more.

All InfraPro thermometers feature laser sighting to pinpoint your exact target. A bright single spot laser to pinpoint the center of your target. |The backlit display shows temperature readings in °F or °C; low-battery indication; underrange and overrange conditions; and and maximum readings.

These compact, lightweight thermometers are easy to carry with you. All thermometers feature a rubber grip and nose that improves resistance to shock, damage, water, and dust.
