Introduction
This type of evaluation is to outline "outline guidelines for the preparation of measuring instruments type evaluation," according to JJF 1016-2009,
JJF 1015-2002 "Measuring Instruments type evaluation and type approval of universal norms" and other norms, standards preparation
Made.
This type of evaluation outline for the first release.
Raw cotton moisture meter type evaluation outline
1 Scope
The outline of the type evaluation method applicable to resistance measuring principle, measuring raw cotton moisture box (pole plate) original
Cotton moisture meter (hereinafter referred to as the analyzer) of pattern evaluation, to other types of means for determining the resistance measurement principle
Instrument may refer to.

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.
