What spectrum of wavelengths does the photodiode/sensor in your pyranometer measure?

Peak sensitivity wavelength: 400 - 1100 nm.

Can this take measurements over a set timeframe? Or only a one time sample?

It really is a one time reading. Point in direction you want and read. It does have a Min an Max function so I guess you can leave it on (battery dependent) and look at it later.

Yes, it comes with a calibration certificate, pre-calibrated before factory.
