A bilateral comparison on illuminance using a photometer between IPT and LABELO

Abstract:
This work presents the result of bilateral illuminance comparison obtained from a photometer calibration. The bilateral comparison was performed comparing the calibration results from the same photometer at LABELO and IPT laboratories, which take part of Brazilian calibration network. Occasionally LABELO was chosen as a pilot laboratory and was responsible to calibrate the photometer at the beginning and end of comparison and define the reference illuminance value of photometer calibration. The illuminance calibration points ranged from 20 to 2000 lx and the comparison evaluation criterion was the normalized error (En numbers). The laboratory measurements are in agreement according to the evaluation criterion.
