GTRテック List of Products and Services

This device can measure the permeability and moisture permeability of gases and vapors under humid conditions using the differential pressure gas chromatography method specified in JIS K 7126-1. It introduces the gases and water vapor that have permeated through the film into the column of a gas chromatograph, where they are separated by component, allowing for the measurement of permeability and transmission rates for each component. It is a device that can evaluate the barrier properties of gases and water vapor in one unit.

The "Belt Break Detection Device" is designed to protect your belt-type vacuum pump, used in differential pressure gas permeability measurement devices (GTR devices), from troubles caused by oil backflow when a sudden belt break anomaly occurs. It can be installed on existing pumps (installation costs are quoted separately). Additionally, we can discuss options for connecting external buzzer and alarm signal outputs. Please feel free to contact us with your requests. 【Features】 ■ Quickly detects anomalies in the vacuum pump's belt break ■ Cuts off the power to the vacuum pump and purges the piping during anomalies ■ The power does not automatically resume, ensuring safety during anomalies on weekends and nights ■ Suitable for users who find it difficult to conduct regular inspections during continuous operation ■ Displays and notifies through an alarm lamp during anomalies *For more details, please download the PDF or feel free to contact us.

• Other inspection equipment and devices

The "GTR-30XFC" is a gas permeability measurement device for polymer electrolyte membranes that can measure various types of gases, including H2, O2, N2, CO2, hydrocarbons, and refrigerants, all in one unit. In addition to measuring humidity on one or both sides of the sample, it is also capable of measuring water vapor permeability. Furthermore, automatic control via a data processing device (computer) is possible. 【Features】 ■ Long-standing track record ■ Compliant with JIS k-7126-2 isobaric method ■ Uses gas chromatography method ■ Up to 1 to 3 measurement cells can be installed *For more details, please download the PDF or feel free to contact us.

The "GTR-11/31" is a gas permeability measurement device that adopts the ASTM method (pressure method) to separate and detect permeating components, utilizing the versatility of gas chromatography. Components separated in the column are detected using a thermal conductivity detector. The amount of permeation for each component is determined from a pre-established calibration curve, allowing for the calculation of permeability and permeance. With this device, you can widely apply it to testing packaging materials for food and pharmaceuticals, research on separation membranes and enrichment membranes, as well as in the research and development sectors for fibers, synthetic chemicals, and resins. 【Features】 ■ Long-standing track record ■ Simultaneous measurement of mixed gas permeability ■ High detection sensitivity ■ Easy handling and operation ■ Measurement possible at low temperatures (freezer option) ■ Automation via computer is also possible (optional) *For more details, please download the PDF or feel free to contact us.
