Micronaire Tester/Cotton Micronaire Tester

The instrument uses the airflow method to test the micronaire value of the cotton, that is, the maturity of the cotton. When the air is applied to the cotton sample, the gas flow is different because the fineness of the cotton is different. By measuring the gas flow, it is possible to test the micronaire associated with it.

Application

Automatic Micronaire Meter, used to determine the micronaire value of cotton fibre. CPU tech. be adoped which can give digital reading and make adjustment of micronaire value (and weight value as well) more easy and convenient. The sampling range is more big, operation more efficient, and test results more accurate. The micronaire value and cotton grade can be displayed directly on the tester, the test data also can be show displayed in the PC when machine connect to the computer.

Standards

(1) ASTM D1448 (Standard Test Method for Micronaire Reading of Cotton Fibers)

(2) ISO 2403 (Textiles — Cotton fibres — Determination of micronaire value)

(3) GB/T 6498 (Cotton fiber micronaire value test method)

Technical Parameters

Features

◆ The instrument uses a high-precision range of electronic flow sensor. The wide range of micronaire measurement can reach 2.7-7.0. Almost all the cotton can be tested on the market. This is the world's most widely used instruments to measure the micronaire.

◆ A key test. Install the sample, and just press a button. Then, you can quickly test the result. The instrument with USB interface, you can use the software to count, analyze test the results , and print the standard test report, you can also save the test report as EXCEL format.

◆ Easy calibration. Quickly calibrate with standard cotton. After calibration, the micronaire value can also be accurately tested in a nonstandard laboratory environment.

FAQ

(1) What is the importance of micronaire value in cotton testing?

Micronaire value reflects both fiber fineness and maturity, which directly affect yarn strength, dye absorption, and fabric quality. It is a key parameter used in cotton grading systems such as ASTM D1448 and ISO 2403, making it essential for both buyers and manufacturers.

(2) How often should the instrument be calibrated?

Calibration is recommended daily or before critical testing batches using standard cotton samples. QINSUN instruments are calibrated before shipment, and routine calibration ensures consistent accuracy, especially when environmental conditions vary.

(3) Can this tester be used outside a standard laboratory environment?

Yes, the instrument is designed to maintain reliable performance even in non-standard environments after proper calibration. However, for best accuracy (±0.03 micronaire), stable temperature and humidity conditions are recommended.

(4) Is the data compatible with quality management systems?

Yes, the tester supports USB data output and can generate reports in Excel format, making it easy to integrate with laboratory information management systems (LIMS) and quality control workflows.

(5) How to choose the right micronaire tester for a textile laboratory?

Key considerations include measurement range, accuracy, testing speed, and compliance with standards such as ASTM and ISO. QINSUN provides factory-calibrated instruments with stable performance and technical support. For selection guidance and application cases, it is recommended to contact engineers for tailored solutions.
