Micron Tester - lab instrument

• 

Compliant Standards

- GB 1103-2007: China's national standard for cotton micronaire value determination.

- ASTM D1448: International standard for cotton maturity testing via air permeability.

- BS 3181: British standard for textile material testing methodologies.

- ISO 2403: Global benchmark for cotton quality assessment procedures.

Product Applications

- Cotton Planting: Used in cotton field management and yield assessment. - Cotton Procurement: Facilitates quality evaluation during cotton purchase. - Cotton Spinning Quality Control: Ensures yarn quality by testing raw cotton maturity.

Testing Principle

The instrument employs the airflow method to determine the micronaire value (cotton maturity index). By applying controlled air pressure to a cotton sample, differences in air permeability due to varying fiber fineness are measured. This allows accurate calculation of the micronaire value, correlating with cotton maturity and quality.

Key Technical Advantages

Broad Measurement Range

- World's widest airflow-based micronaire range: 2.0–7.5 - Covers 99% of commercial cotton varieties globally.

Precision & Efficiency

- Accuracy: ±0.03 micronaire value (under standard lab conditions) - Test time: ≤15 seconds per sample

User-Friendly Design

- One-touch operation: Sample loading → auto-test → result display - USB connectivity: Export data to Excel or generate PDF reports via included software

Robust Calibration

- Quick calibration using certified reference cotton standards - Stable performance in non-laboratory environments (e.g., field stations)
