If you’re calibrating IR guns at cold temperatures, you’ll love our new 9133. With solid-state cooling technology, this new IR calibrator reaches –30°C (22°F) in normal ambient conditions. With a conveniently located dry gas fitting on the front bezel, ice build up on the target can be avoided. At the upper end of its range, the 9133 provides stable temperatures to 160°C (320°F). 

With heating and cooling times of about 15 minutes from ambient to either extreme, the 9133 gets you to temperature quickly and performs when it gets there. Compare your IR devices to the temperature display—it’s factory calibrated to be within ±0.4°C (±0.7°F). 

No other IR calibrators give you this level of precision in such compact packages. Whatever your temperature application, trust a Hart product to solve it. 

Whether you’re using in-line or handheld infrared pyrometers, you need good calibration standards to verify their accuracy. Our new portable IR calibrators provide stable blackbody targets for calibrating noncontact IR thermometers from –30°C to 500°C. 

These new units feature a large, temperature controlled blackbody target with a diameter of 2.25" (57 mm), which offers a large field of view area for optical variations in infrared thermometers. The emissivity of the isothermal target is set at 0.95 (±0.02%), and the target temperature can be controlled in set-point increments of 0.1° from –30°C to 500°C. 

For even higher precision, a well is located directly behind the blackbody surface for contact calibration of the blackbody. 

These units are as easy to use as “point and shoot.” Simply set the desired blackbody temperature from the convenient front panel control buttons, wait a few minutes for equilibrium, and point the gun at the target. The radiated energy from the blackbody is measured by your IR thermometer. Simply compare its reading to the display on the blackbody and record the difference.
