The Fluke Calibration 9133156 Portable Infrared (IR) Calibrator with Dry Gas Purge, -30 °C to 160 °C at 23 °C ambient (-22 °F to 320 °F at 73 °F ambient), 115VAC provides a stable, blackbody target for calibrating noncontact IR thermometers.

The 9133-156 features a large, temperature controlled blackbody target with a diameter of 2.25 in. (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°. For even higher precision, a well is located directly behind the blackbody surface for contact calibration. Using an optional calibrated PRT and readout device, target accuracy of ±0.075 °C can be achieved.

The Fluke Calibration 9133-156 is 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.

If you are calibrating IR guns at cold temperatures, you will love the Fluke Calibration 9133-156. With solid state cooling technology, this IR calibrator reaches -30 °C (22 °F) in normal ambient conditions. With a conveniently located dry gas fitting on the front bezel, the 9133-156 will not build up ice on the target. At the upper end of its range, the 9133-156 provides stable temperatures to 160 °C (320 °F).

With heating and cooling times of about 15 minutes from ambient to either extreme, the 9133-156 gets you to temperature quickly and performs when it gets there. Compare your IR devices to the temperature display. which is factory calibrated (NIST traceable) to be within ±0.4 °C (±0.7 °F).
