Easy to use, accurate and repeatable measurements
I have compared this meter to several spectrometers and calorimeters. From my tests, I believe this meter is more accurate than my other devices. Its measurements are repeatable and scale perfectly with an increase in luminosity. I'll add it is very easy to use. Excellent device, highly reccomended.
