The Water Vapour Permeability Tester is a constant temperature and humidity instrument designed to evaluate the moisture permeability of waterproof-breathable textiles, sportswear fabrics, polymer films, processed paper, and other moisture-resistant packaging materials. By sealing samples onto cups filled with anhydrous calcium chloride and exposing them to controlled climate conditions, the instrument calculates water vapour transmission through weight change. With precise PID environmental control, adjustable airflow, and a rotating sample holder, it ensures highly stable, repeatable, and multi-standard test results.
Application
Suitable for testing water vapour permeability of sportswear fabrics, waterproof-breathable textiles, outdoor functional materials, composite membranes, polymer films, processed paper, and various moisture-proof packaging materials. Its rotating sample holder and adjustable airflow ensure uniform test conditions, making it ideal for high-performance moisture management fabrics.

ISO (Equivalent methods referring to ASTM E96)
Features
Compatible with ASTM, ISO, JIS and GB standards for moisture permeability testing.
Rotating sample holder with adjustable speed for more uniform testing than fixed holders.
Adjustable airflow with imported wind speed sensors for excellent accuracy and stability.
PID temperature and humidity control to minimize fluctuations and prevent overshoot.
Built-in calibration functions to prevent long-term sensor drift.
High-precision temperature and humidity sensors provide stable and reliable data.
SCM control system with a color touch screen for intuitive and intelligent operation.
Automatic calculation of WVT, WVP and PV values directly on the touch screen.
PC software for data recording, temperature/humidity curve tracking and report printing.
