The Optical Properties Measurement OP4255 combines measurement of three visual paper properties — formation, opacity, brightness — in one compact head package.
The Optical Properties Measurement OP4255 provides continuous and repeatable measurement of sheet formation on-line, allowing progressive papermakers to capitalize on this dimension of process visibility. In addition, it simultaneously measures opacity and brightness, resulting in substantial economic and quality benefits. The sensor features high speed measurement and resolution that provides process variability information not previously attainable.
