General
PGS-100 is the state of art sunphotometer with the adopted grating as the spectrometer system.
It can be loaded on the sun tracker ASTX-1 (or ASTX-2) for the measurement of spectroscopic direct solar radiation.
Basic software operates on the Windows PC, and the outdoor continuous observation is available.
Data will be stored into the PC via RS232.
