= Digital  Concrete Air-Meter (DY-300) =

 : Air content in fresh concrete is commonly measured in the field using the pressure method. The pressure method is practical for field-testing most concretes.

 - Original volume of Air in the sample is determined by the principle of Boyle’s Law.

- This Meter(DY-300) quickly determine percentage of entrained air in freshly mixed concrete. And has a multi-range feature to accurately  measure entrained air up to 9.9% by Digital Measuring System.
