3.1 moisture content mass moistureweight Water containing raw cotton quality time. 3.2 dry mass dryweight Raw cotton by a certain method of removing the water quality after. 3.3 Regain moistureregain Under specified conditions measured raw cotton moisture content, quality and moisture to the dry mass of the difference sample on dry basis Amount expressed as a percentage.

4 Overview

Analyzer is the use of cotton fiber regain its resistance value was negatively correlated with changes in the law in a certain amount of fiber, Under pressure, voltage, and temperature conditions of the test area, measuring the resistance of cotton fiber, cotton fiber moisture regain indirectly measure a Kinds of instruments. Meter pole plate mainly by moisture sensor, temperature and humidity sensors, pressure measuring mechanism and electronic Circuit and display parts and other components. Tester is mainly used for cotton purchase, processing, textile, quality inspection departments to quickly regain raw cotton Determination. ......
