Chapter 1 Introduction
The USTER® HVI 900™ Instrument measures the seven physical
characteristics defined by the United States Department of Agriculture
(USDA) in its cotton marketing system. It measures fiber length, strength,
length uniformity, elongation, micronaire, color, and trash. All of these
properties are important in fiber research, in the development of
improved fiber blends, and in verifying that purchased fiber meets
specifications.
The HVI 900 fiber test system offers precise and reliable automated
operation with computer controlled calibration and diagnostics. All
functions are controlled by dedicated microprocessors to simplify
operation and to provide flexibility in testing parameters. The computer
system has both a 3.5-inch and a hard disk drive.
