Abstract

Calibration of light intensity measuring instruments (lux meters) is essential to ensure accurate lighting measurements in various work environments. In this study, a lux meter calibration was performed using the comparison method with a standard lux meter, the Gossen Mavolux 5032B, following the PK.F-02:2021 standard from the Indonesian National Standardization Agency (BSN). Two units were tested: the Gossen Mavolux 5032B and the KYORITSU 5202. The results showed that the Gossen lux meter remained within the acceptable deviation tolerance across the entire calibration range, indicating that the device is still accurate and fit for use. In contrast, the KYORITSU lux meter showed significant deviation at low light intensity levels, indicating lower accuracy in that range. The calibration was conducted in a controlled room with temperature and humidity maintained according to standards, and the data was analyzed using Microsoft Excel. The measurement results emphasize the importance of regular calibration to ensure measuring instruments remain accurate and reliable.
