AMCO Clear® Certified Reference Standards for Turbidity Meters

AMCO Clear® Certified Reference Standards are the US EPA approved alternative to formazin products for the calibration of turbidity monitors. AMCO Clear® is a non hazardous aqueous polymer suspension that is extremely stable and remains suspended without shaking or inverting. On a quality instrument the obtained value remains unchanged since there is no particle settling taking place.

AMCO Clear® is NIST traceable: Particle shape, size and distribution are consistent from lot to lot and traceable to NIST particle standards. Optical Density of each value is consistent and determined on a Certified Visible Spectrophotometer.

AMCO Clear® is available, not as a concentrate such as formazin, but in the ready to use value of your choice. Not only are the specific calibration points for your particular instrument available but many other values as well ---- from 0.02 to 10,000 Turbidity Units.

AMCO Clear® is preferred by many governmental agencies for calibration of their turbidity sensors used in Water Quality and Suspended Sediment Concentration and Transport.

AMCO Clear® is also available in sealed glass vials for use as Secondary Standards. These allow the technician to verify instrument calibration on a daily basis without using large amounts of the Primary Standard suspension.
