Page 3: Introduction
INTRODUCTION The LPUVB02 radiometer measures the global irradiance in the UVB spectral range on a flat surface (W/m ). In particular, the instrument spectral sensitivity is centred at 304 nm with a 5 nm bandwidth (FWHM - Full Width at Half Maximum). -

Page 10: Maintenance
Read instructions at chapter 3 about how to replace the silica-gel crystals. Silica-gel typical lifetime goes from 2 to 6 months depending on the environment where the radiometer works. To exploit all the radiometer features, it is highly recommended that the calibration be checked annually. LPUVB02 V2.0... -
