GTRテック Company Profile

A pioneer manufacturer of transmittance measurement devices equipped with various transmittance measurement instruments.

Our company was established as a specialized manufacturer of "gas, water vapor, and liquid permeability measurement devices." Currently, we have expanded our offerings to include not only gas permeability but also water vapor permeability, as well as the permeability of VOC liquids using PV cells and the permeability of VOC vapors using T cells. Furthermore, we have developed new products such as the GC Shed (GC Shed: patented in Japan and the United States), which can measure the permeability of gases in tubes and pipes, as well as liquids like gasoline and VOCs; a permeability measurement device for electrolyte membranes used in fuel cells; a pinhole detection device for electrolyte membranes; and a permeability measurement device for Li-ion batteries and electrolytes, thereby broadening the application range of permeability measurement.
