Grating Sun Photometer
[Temporally out of production and new model is under development]
PGS-100 is the highly efficient Sunphotometer which adopted grating as
the spectrometer system.
Basic software operates on Windows and can perform outdoors continuous
observation.
Data can be transferd and stored to PC, via RS232C.
[Feature]
- Measurement of the spectral intensity of direct normal irradiance (DNI)
- Messurement of the atmospheric turbidity
- Grating is used for the spectrometer system.
