Turbidity Standards

See our AMCO Clear Turbidity Standards. EPA 180.1 approved, NIST-traceable primary standards designed for reliable calibration of turbidity meters. Produced as stable aqueous polymer suspensions, they require no preparation or mixing -- just open and start calibrating. Each lot is verified for photometric accuracy using UV-VIS spectroscopy.
