DESCRIPTION: The Optek DT9011 is a precision, bench-top turbidity meter that features an advanced, triple-beam optical design that measures forward scatter (11°), side scatter (90°) and direct (0°) light. The turbidity meter effectively measures a broad range of constituents that contribute to turbidity and fine haze. From line to lab, Optek instruments monitor wine color, solids concentration, turbidity, haze, clarification and filtration.
