Model 9133 certifies infrared thermometers to -22 oF (-30oC) in normal ambient conditions. At the upper end of its range, the calibrator provides stable temperatures to 302oF (150 oC). The device is factory calibrated (NIST traceable) to be accurate to +/-0.7oF (+/-0.4oC) and has heating and cooling times of about 15 min. Model 9133 also has a large 2.25" (57 mm) temperature-controlled blackbody target with an emissivity of 0.95. CIRCLE 201
