GB/T 12704 – Test Method for Water Vapour Transmission of Textiles
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.
