Electronic Lea Strength Tester

The Electronic Lea Strength Tester is a high-precision textile testing instrument designed to measure the peak breaking force and elongation of yarn in skein form (lea). Built with a rugged, ergonomic tabletop design, it operates on the standard CRE (Constant Rate of Extension) principle. The microcomputer-controlled solid-state system with alphanumeric LCD display allows user-friendly operation and accurate measurements. Its maintenance-free inline drive and clutch-driven traverse mechanism ensure smooth sample handling. With selectable force and elongation units, computer connectivity, and compliance with ASTM D1578 and IS 1671 standards, this tester is ideal for textile laboratories and quality control departments for reliable yarn strength testing.
