Gas Permeability Tester

Model : EKT-2128BR
The EKT-2128BR Gas Permeability Tester is designed to ISO 2782-1 standards to measure the gas transmission rate of rubber films. It features 3 independent test sample holders, an ultra-stable Hot Water Circulation temperature control system, a high-performance vacuum pump, and advanced Windows software for automated pressure-time curve calculation.

High-Stability Hardware & Intelligent Software

Hot Water Circulation & Multi-Station

Because gas transmission is highly sensitive to thermal fluctuations, the EKT-2128BR abandons standard air heating in favor of a superior Hot Water Circulation system, ensuring an exceptional temperature accuracy of ±0.3°C. Coupled with a powerful vacuum pump and 3 independent sample holders, it maximizes both precision and laboratory throughput.

Advanced Windows Operation System

The user-friendly interface handles tests that can run up to 999 hours seamlessly, offering multi-language support (English, Traditional & Simplified Chinese).

  • Auto-Calculation: Automatically calculates results and draws the pressure vs. corresponding time curve.
  • Data Management: Save, reload, and compare historical curves instantly.
  • Custom Reporting: Simple edit program allows users to design reports with specific data, logos, and formats.

Frequently Asked Questions: EKT-2128BR

Why does this machine use "Hot Water Circulation" instead of air heating? ▼
Water has a significantly higher specific heat capacity than air, meaning it transfers and holds heat much more effectively. In permeability testing, even a 1°C fluctuation can drastically alter the gas transmission rate. The hot water tank and pump system completely surrounds the testing chambers, providing an ultra-stable, uniform temperature profile (accuracy of ±0.3°C) that dry air incubators simply cannot match.
How does the software handle tests that last for several days? ▼
Highly impermeable materials like butyl rubber inner liners may require very long testing periods (the machine supports up to 999 hours). The dedicated Windows software runs robustly in the background, continuously logging the micro-changes in pressure over time. Even for prolonged tests, it automatically plots the pressure-time curve and calculates the final transmission rate without requiring operator intervention.
