About This Product
Lea strength is one of the main properties that decide whether a yarn suits its final use. To test it, a lea of fixed length is made on a wrap reel and then placed over two pins, one attached to the load measuring arrangement and the other moved by a motor-driven screw, and the maximum load is registered. Metric and imperial leas have different swift perimeters, so the tester carries a separate moving pin for each type. Students use it to compare the strength of different yarns. School Lab Equipment India can export the Lea Strength Tester to education buyers in Bhutan, Cameroon, Panama, Afghanistan, Saudi Arabia and Paraguay.
Frequently Asked Questions
Q1. What does the Lea Strength Tester measure?
It registers the maximum load on a lea made from the yarn, which gives the lea strength of the yarn.
Q2. Which leas can it test?
Two movable pins are provided: one for metric leas of 1 metre swift perimeter and one for imperial leas of 1.5 yards swift perimeter.
Q3. What happens at the end of the pin travel?
The motor stops automatically at the extreme positions of the moving pin.
