Product Description
Water Vapor Transmission Rate WVTR Tester
Application
It is used for Water Vapor Transmission Rate tests of various fabrics, membrane materials and coated fabrics.
Test Standards
GB/T 12704, ASTM E 96, JIS L 1099, BS 7209
Features
- Touch screen control, Chinese and English menu, man-machine dialogue mode, convenient operation.
- Rotating sample placement frame, 1 ~ 15r/min speed adjustable, the test results are more uniform than fixed sample frames.
- High precision temperature and humidity sensor, control using PID algorithm with small fluctuation, effectively preventing temperature and humidity overshoot.
- Includes temperature and humidity calibration function to avoid sensor deviation caused by long-term use.
- MCU control, color touch screen operation, modular design, temperature and humidity digital setting, intelligent control, real-time display of temperature and humidity and timing time.
- Input parameters on the touch screen to calculate WVT g/(h.m²), WVP g/(h.MHg.m²), PV g.cm/(h.MHg.m²) value.
- Instrument is equipped with PC software, temperature and humidity curve can be recorded, convenient for large data report calculation and printing, suitable for various standards and measurement methods.
