AMCO CLEAR® products are the highest quality water calibration standards available.
AMCO CLEAR® is an EPA approved primary standard chemical product for calibration of turbidity sensors. It is safe, non-toxic and disposable. It is easy-to-use, requires no dilution or resuspension, and it is available in a wide range of values.
It is NIST traceable to particle size/distribution and optical density, and its inherent stability means it does not settle from suspension. It has a guaranteed one year shelf life.
These convenient submicron polymer suspensions are non-toxic primary calibration standards approved by the US EPA for drinking water analysis for turbidity, and preferred by the US Geological Survey for turbidity and sediment transport analysis.
In addition, GFS also sells turbudumeters, instrumentation and testing equipment for water quality applications.
