【Scope of application】:
It is suitable for thermal and moisture resistance testing of flat materials such as textiles, clothing, bedding, sleeping bags, upholstery, films, coating materials, foams, leather, textiles with multi-layer fabric combinations. The detection accuracy is much higher than the standard, which is an ideal instrument for measuring the thermal and humidity performance indicators of textile physiological comfort.
[Meet the standard]:
GB/T11048-2008 ISO11092 ASTM F1868(A-E) 等
[Instrument features]:
1. The instrument adopts a high-precision temperature sensor, which greatly improves the testing accuracy, repeatability and stability of the instrument.
2. The test plate is made of special stainless steel material powder metallurgy microporous and perforated plate, which highly simulates the skin sweating effect. At 20°C, the radiation coefficient of the surface of the test plate was measured to be higher than 0.4 by beams with a wavelength range of 8um to 14um and hemispherical reflection. Compared with test boards made of other materials, it avoids problems such as rust and patina (patina) caused by long-term moisture resistance tests and blocks the test board.
3. Microcomputer control and data processor are used to directly measure and calculate the performance of the specimen. (thermal resistance, moisture resistance, moisture permeability, moisture permeability index, heat preservation rate, heat transfer coefficient, crohn value) does not need to be manually calculated.
4. The large screen color LCD touch screen display can store all the data and final statistical results during the test process, and provide real-time query.
5. The integrated design of high-precision constant temperature and humidity chamber and instrument ensures the stability of test results.
6. Real-time and rapid dynamic collection of temperature and humidity data, multi-point independent calibration, effectively ensure the authenticity of test results
7. Imported motor drive lifting system is used to quickly cooperate with the test of different thickness specimens
8. Automatic water level supply system, error < 1mm
9. The test data can be directly output by the printer, which can realize the direct control operation of the instrument computer and display various temperature and humidity balance curves.
