ATM Test Sieves

 

ATM Test Sieves

 

  • Accurately produced in the U.S.A.

  • Made in accordance with established ASTM E-11 specifications

  • Die-formed frames for guaranteed fit and superior quality


Assured Accuracy of Opening


In the past, it has been very difficult and impractical for sieve manufacturers to be sure the wire cloth in the sieve was within the ASTM tolerances. Using sophisticated optical inspection equipment, a practical method has been developed to inspect each sieve prior to shipment to assure quality and meet ASTM tolerances. A specially built Image Analyzer is used for consistent accuracy, sieve after sieve. All Test Sieves are made in accordance with specifications established by ASTM E-11.


Test Sieve Frames


ATM sieve frames are die formed for guaranteed fit and superior quality. All test sieves are packaged in sturdy cartons for safe shipment. These cartons also provide the user with handy and protective storage containers.
