Permeability Testers: Gas Diffusion Permeameter
Gas Diffusion Permeameter
The Gas Diffusion Permeameter (GDP-V1) is an advanced instrument specifically designed to measure the permeability of gases through membrane-like materials under static and dynamic conditions. Equipped with a high-vacuum pump, it ensures precise detection of even the smallest gas permeability rates.
By utilizing indirect pressure measurements instead of direct flow measurements, the GDP-V1 achieves unmatched accuracy, making it an essential tool for industries and research facilities focused on gas transport properties in various porous materials.
Its versatile sample compatibility, automatic pressure regulation, and temperature control options make it suitable for testing materials in forms such as flat sheets, hollow fibers, and tubes.
Key Features:
- High Sensitivity Detection: Indirect measurement of gas transmission rates using precise pressure transducers.
- Versatile Sample Testing: Supports flat sheets, hollow fibers, and tube samples.
- Wide Pressure Range: Operates efficiently from 0 to 100 PSI.
- Accurate Measurements: High-resolution pressure transducers with 0.000017 accuracy.
- Automatic Controls: Automated vacuum and pressure regulation systems.
- Stable Conditions: Optional temperature control system (0–80°C) for consistent testing environments.
- User-Friendly Interface: USB communication and compatibility with Windows operating systems.
- Calibration and Adjustment: Built-in calibration and auto-test parameter settings.
