- AMCO Clear is a unique, non-toxic low-level turbidity standard that reliably measures turbidity from 0.02 NTU to 10,000 NTU. It is available as primary and secondary standards for turbidimeters. - The standards are safe, non-toxic, and disposable. They do not require mixing or preparation and have a stable one-year shelf life. They are accurate to 1% and available in a wide range of values. - Independent tests show AMCO Clear is superior to other standards like Formazin. It has a particle size distribution that is better for calibrating water analyzing turbidimeters.

2. Serving the Water Industry: AMCO Clear® is the unique, non-toxic low-level turbidity standard that can reliably read from 0.02 NTU to 10,000 NTU every time. Available as primary and sealed secondary standards for all turbidimeters.

3. Benefits: If you are in the business of formulating products, there is no need to waste your time preparing and validating calibration standards. We can make high quality standards for nearly any analyzing instrument that operates under the principle of light scatter.

4. Benefits: Safe, non-toxic and disposable Requires no mixing or inverting Easy-to-use / No dilutions or preparations Stable - does not settle out of suspension Accurate to 1% lot-to-lot Guaranteed one-year shelf life Available in a wide range of values N.I.S.T Traceable Custom standards availables available

5. Benefits: AMCO is Uniform The polymer suspension is a better standard for the calibration of surface source water analyzing turbidimeters. The primary reason is its particle size distribution, 0.02 micron (m) to 0.2m and a mean size of .121m. Formazin is not

6. Independent Tests Show Amco Clear® is Superior AMCO Clear ® has been in use for 20 years. Syracuse University (sponsorship of AwwaRF) conducted a one-year study of the performance of all EPA calibration standards and turbidimeters. AMCO Clear ® was the Clear Favorite in every case.

7. Benefits: The final consideration is safety, the AMCO Clear ® polymer calibration standards are environmentally safe. Formazin in any form is toxic.
