MN-BII Blackness Meter/nigrometer
MN-BII reflex blackness instrument is a kind of high sensitive reflectivity measuring instrument, a measure of degree of black and dark grey black on the surface of the object.The measurement accuracy of the instrument is well correlated with the Densichon type reflective photometer specified by astm.The measuring circuit of the instrument adopts high precision, low drift integrated operational amplifier and LARGE scale integrated circuit A/D converter, so that the instrument reading is stable, reliable and easy to use.
