The breaking load at break are one of the most important property of any yarn., cord or thread . These are usually determined either by equipment having a constant rate of traverse or by equipment having a constant rate of loading.

The “ASIAN” Lea Strength Tester is suitable for determining the tensile strength & elongation of tea by using the constant rate of transverse principle. This equipments that have two grip one of which to the load measuring device and the other grip attached to the movable nut which is move it and fixed speed  with  the help of a motor  worm reduction gearbox and screw arrangement.

The load applied on the test specimen is sensed by load cell and is indicate on a digital display. The controller is microproccer based and has the facility of over load protection, peak hold and auto calibration. The load directly indicated in kilograms or Newton.

The elongation of the test specimen is measured on a digital indicator fixed on the frame of the tester, which indicates the distance between the grips.

   The variable speed model speed is vary by a knob fixed on the panel and the speed also digitally indicated on the control panel.

     Various built in safety arrangements such as over travel protection, are provided.

     The tester is finished in painting, powder coating and bright chrome/zinc plating to give the apparatus a corrosion resistant finish. It is supplied complied which electrical. Which include micro-switches, push buttons and contactors for safe and convenient operation.

      A variety of grips suitable for holding different materials are offered as optional accessories.
