Lea & Single Yarn Strength Tester

 

This electrical single-yarn tester is an ideal machine, which can test yarn’s breaking strength, elongation rate and other technology targets.

The machine adopts testing principle of constant rate of elongation (CRE) and microcomputer to control, settle automatically and print data. It is programmed easily. And the tester is precise, fast and convenient. The machine has the function of protecting data in the machine when the power is lost. (It can memorize data when the power is lost suddenly.)
 

Standard: ISO2062, ASTM, BS, JIS, AS, CAN/CGSB.

Technical Parameter:

  1. The max testing strength: 3000cN.

  2. Error of strength <=±1%.

  3. Gauge between up and down gripper: 250mm±1mm, 500mm±1mm (It can be selected randomly.)

  4. Pre-tension’s scope: 1cN~100cN

  5. Constant breaking time: 20s±3s or 10s±1.5s (It can be selected randomly.)
