This meter is a precision instrument for measuring light intensity. It's applications include solar radiation measurement、 solar research、 physical and optical experiments、 meteorology、 and agriculture. It can also be used to measure glass light intensity to verify glass properties. E.g.、 measurement of light intensity passing through vehicle windows.
