PGS 100 is a spectrophotometer for the routine automated measurement of the spectrum of direct solar radiation. It must be mounted on an automatic sun tracker, such as the Kipp & Zonen SOLYS 2 or 2AP.

PGS 100 comes with Windows control and data logging software. The instrument must be connected via the RS 232 port to a computer (not included) running the supplied software in order to operate. The measured spectra are displayed directly on-screen and can be analysed using wavelength selection tools.

PGS 100 provides spectral data that can be post-processed by the user (software not included) to derive a variety of parameters, including:

• optical depth
• energy distribution
• absorption by atmospheric gasses
• aerosol properties

Main features :

• Direct solar measurements using an integrated solar tracker with active sun sensor correction
• Temperature stabilised spectrophotometer with no moving parts
• Wavelength range 350 - 1050 nm, wavelength accuracy 0.5 nm, bandwidth 3.6 nm
• Programmable measurement times, cycles and integration time
• Logging of up to 20 user-defined wavebands
