Micron Tester
The Micron Tester is a precision instrument designed for determining the micronaire value of cotton, a key indicator of fiber fineness and maturity. Using the airflow method, it measures the air permeability of cotton samples to calculate micronaire values accurately, providing critical information for cotton quality assessment, procurement, and spinning quality control.
Application Scenarios
(1) Cotton planting and field management: testing cotton bolls, harvested fiber, and sample bales for fineness and maturity
(2) Cotton procurement: evaluating raw cotton bales, seed cotton, and ginned cotton for micronaire value before purchase
(3) Cotton spinning mills: testing raw cotton, carded slivers, and roving for fiber maturity and uniformity to ensure yarn quality
(4) Cotton breeding and R&D: analyzing experimental cotton lines, hybrid fiber samples, and progeny varieties for fiber development studies
(5) Laboratory quality control: classifying cotton fibers from commercial suppliers, testing blended cotton lots, and verifying fiber fineness consistency
(6) Educational and research institutions: cotton fiber testing for teaching experiments, student projects, and textile engineering demonstrations
(7) QC and inspection institutes: standard-compliant testing of cotton batches, imported/exported cotton, and vendor comparison
(8) Comparative evaluation: assessing cotton from different regions, farms, gins, or suppliers to ensure consistent fiber quality
Compliance Standards
(1) GB 1103-2007 — Cotton micronaire value determination (China national standard)
(2) ASTM D1448 — Cotton maturity and fineness testing via airflow method
(3) BS 3181 — British textile material testing standards
(4) ISO 2403 — International cotton quality assessment procedures
(5) ICAC Recommended Practices — Standard procedures for cotton fiber testing
Key Features
(1) Broad Measurement Range: Airflow-based micronaire range 2.0–7.5 covering nearly all commercial cotton varieties
(2) High Precision & Efficiency: Accuracy ±0.03 micronaire; ≤15 seconds per sample
(3) User-Friendly Operation: One-touch sample loading, automatic testing, and results display
(4) Data Connectivity: USB output for Excel export and PDF report generation
(5) Robust Calibration: Quick calibration with certified reference cotton; stable in field or lab environments
