Product description
The NELD-NPR163 nitrogen permeability tester is independently developed by NELD based on the GB36900.2-2018 "Concrete High Integrity Container for Low-and-Intermediate Level Radioactive Solid Wastes" standard. The nitrogen permeability method measures concrete's resistance to gas permeation by testing the gas permeability of concrete. The tester uses specimen fixture made of 304 stainless steel, with high accuracy digital acquisition gauges, pressure-resistant inflatable rubber capsule, and digital soap film flow meter, all generating accurate results. The product deploys a scientifically exquisite design, providing a simple and easy operation. This is the ideal experiment instrument for scientific research units and quality-inspection institutions.
