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 standard
GB/T 12704,ASTM E 96,JIS L 1099,BS 7209
Features
1, touch screen control, Chinese and English menu, man-machine dialogue mode, convenient operation.
2, rotating sample placement frame, 1 ~ 15r/min speed adjustable, the test results than the fixed sample frame uniform.
3, high precision temperature and humidity sensor, control using PID algorithm fluctuation is small, effectively prevent temperature and humidity overshoot.
4, including temperature and humidity calibration function, can be very good to avoid the sensor deviation caused by long-term use.
5, 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.
6. Input parameters on the touch screen to calculate WVT g/(h.m²), WVP g/(h.MHg.m ²), PV g.cm/(h.MHg.m ²) value.
7, the instrument is equipped with PC software, temperature and humidity curve can be recorded, convenient for a large number of data report calculation and printing, suitable for a variety of standards and measurement methods.
