Product positioning:

GTR-3 Breathability/Gas Transmittance TesterIt is a laboratory instrument specialized in accurately measuring the gas permeability of packaging materials such as films and sheets. It is a key equipment for product quality control and research and development in multiple industries such as packaging, new materials, photovoltaics, and healthcare.

Core functions:

• Accurate testing: Accurately measure the permeability of materials to oxygen (O ₂), nitrogen (N ₂), carbon dioxide (CO ₂), and even flammable and explosive gases (customized).

• One machine dual testing: Two key parameters, gas permeability and permeability coefficient, can be obtained simultaneously in one test.

• Efficient three chamber: Adopting a unique VOV three chamber independent design, the three testing chambers can be tested independently at the same time, greatly improving detection efficiency and supporting parallel testing of different materials or gases.

• Wide applicability: With a wide testing range and precise temperature and humidity control, it can test various materials ranging from high barrier properties to high breathability.
