Electronic Single Fiber Strength Meter
The Electronic Single Fiber Strength Meter is a precision instrument designed to measure the mechanical properties of single fibers, including breaking strength, elongation, and modulus. It integrates high-precision pneumatic clamps, microcomputer control, and real-time data acquisition to provide accurate, repeatable, and reliable fiber testing for research, quality control, and textile manufacturing applications.
Application
This instrument is widely used in:
Textile fiber research and development laboratories.
Quality control in cotton, wool, silk, synthetic, and specialty fiber production.
Determination of single fiber properties for spinning, yarn production, and composite materials.
Educational institutions for teaching fiber mechanical properties.
Textile testing agencies and standards compliance verification.
Standards
The Electronic Single Fiber Strength Meter complies with:
GB/T 14337: Single fiber strength determination
GB/T 9997: Cotton fiber testing
GB/T 13835.5: Wool fiber testing
GB/T 21120: Silk fiber testing
ISO 5079: Textile – single fiber strength determination
ISO 11566: Wool fiber testing
ASTM D3822: Standard test method for tensile properties of single fibers
BS 4029: British single fiber testing standard

Maintenance
Regularly inspect and clean pneumatic clamps to prevent contamination.
Calibrate the force measurement system periodically using standard fibers.
Keep the instrument in a dust-free, dry environment.
Ensure stable AC power to prevent measurement errors.
Avoid mechanical shocks and handle the LCD and printer with care.
