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.

is this meter has a calibration certificate?

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

Is this tenmars tm206 brand authentic? i dont see the logo in your pictures, please confirm

Yes, we are the Brand owner of TENMARS, the LOGO of TENMARS is in the main unit and also in the packaging.

Great device - lots of bang for your buck, and great support!

I purchased this on the advice of a "biohacker blogger" to test the irradiance of photobiomodulation units. While they aren't meant to be completely accurate, because of the various factors involved in testing, for the price you pay, and the conditions, they do give you a very usable result. They're definitely recommended for the purpose described.Also - when I was having problems with the device, I received a very fast reply from customer services - and several follow ups to make sure that the problem had been solved.I recommend both the product and the company.
