Small, compact design
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, 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. Using an optional digital RTD thermometer, target accuracy of ±0.075°C can be achieved.
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.
