Micronaire Module
Micronaire is measured by relating air flow resistance to the specific
surface of fibers.
An air stream is passed through a known mass of fiber confined in a
chamber of fixed volume.
The pressure differential across the chamber is then related to the
specific surface of the fiber to determine the micronaire value for cotton.
•
A precision electronic balance is provided to weigh the cotton
sample.
•
The balance is protected by an acrylic guard.
•
Once the cotton sample is weighed, it is placed in the micronaire
chamber (located below the balance) and tested for micronaire
measurements.
