About This Product
Waterproof protective footwear and gumboots must keep water out when the wearer walks through water, so the body of the footwear is checked for leaks. In this test the top opening is sealed with an end plug and the footwear is lowered into a water bath up to its top edge. Compressed air at the specified pressure is passed in, and the tester watches for air escaping as a steady stream of bubbles. Large steel balls placed inside keep the footwear upright in the bath. School Lab Equipment India can export the Leak Proofness Tester to education buyers in Malawi, Philippines, Qatar, Serbia and Palestine.
