HBY TextileWater Vapor Permeation Instrument


HBY Textiles Water Vapor Permeation Instrument is used to measure the moisture permeability of various fabrics (including moisture-permeable coated fabrics) such as medical protective clothing and jackets, as well as non-woven fabrics such as cotton and space cotton.

Standards compliant:
GB 19082-2009 Test method for technical requirements of medical disposable protective clothing
GB/T 12704.1-2009 Textiles - Test method for moisture permeability of fabrics - Part 1: Moisture absorption method
GB/T 12704.2-2009 Textiles-Test method for moisture permeability of fabrics-Part 2: Evaporation method ASTM E90, JIS L1099A, BS 7209, JIS L1099B

technical parameter
1. Touch screen control, Chinese and English menus, man-machine dialogue mode, easy to operate.
2. High-precision temperature and humidity sensor, the control adopts PID algorithm, the fluctuation is small, and the temperature and humidity overshoot is effectively prevented.
3. With temperature and humidity calibration function, it can well avoid sensor deviation caused by long-term use.
4. PLC control, color touch screen operation, modular design, digital setting of temperature and humidity, intelligent control, real-time display of temperature and humidity and timing. Cooling method: air cooling
5. Input parameters on the touch screen to calculate the values ​​of WVT g/(h.m²), WVP g/(h.mmHg.m²), PV, g.cm/(h.mmHg.m²).
6. The instrument can record the temperature and humidity curve, which is convenient for the calculation and printing of a large number of data reports. It is equipped with a micro-printer and is suitable for a variety of standards and measurement methods.
7. Adjustable temperature control accuracy/resolution: -40～150℃±0.5℃/±0.1℃
8. Adjustable humidity Relative humidity: 20～98%RH; ±2%RH
9. Air velocity in the box: 0.1～0.8m/s
10. Configuration: 1. The number of layers and the number of moisture permeable cups: 4 single layer (national standard)
