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

The Micron Tester is widely used in:

Cotton planting and field management for yield and quality assessment.

Cotton procurement to evaluate raw cotton quality during purchase.

Cotton spinning mills to ensure yarn quality by testing raw cotton maturity.

Research and development in cotton breeding and textile studies.

Laboratory quality control for cotton fiber classification.

Standards

GB 1103-2007: Cotton micronaire value determination (China national standard)

ASTM D1448: Cotton maturity and fineness testing via airflow method

BS 3181: British textile material testing standards

ISO 2403: International cotton quality assessment procedures

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 test, and result 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.

Test Procedures

(1) Weigh 5 g of cotton sample and condition according to standard requirements.

(2) Load the sample into the test chamber.

(3) Start the device using one-touch operation.

(4) The instrument automatically applies airflow and measures air permeability.

(5) View the micronaire value on the display.

(6) Export results via USB if needed.

(7) Clean and prepare the chamber for the next test.

Maintenance

Regularly check airflow channels for blockages.

Use certified reference cotton for routine calibration.

Wipe the sample chamber with a soft, dry cloth; avoid moisture.

Ensure stable power supply to prevent instrument errors.

Store in a clean, dry environment to maintain precision.
