Brightness Tester& Cover Factor Meter for Hessian / Raw Jute

Additional Details

 The ability to the L.e.d is stabilized in order to radiate settled force and there is one semiconductor light sensor.

 For measuring splendor, an exhibit of high force monochromatic L.e.d.s is altered in a round manner around the focal point is a light sensor.  The sensor and the L.e.d. show are settled on top and the light falls on the test piece.
