Textile thermal and moisture resistance tester can be used to test thermal resistance and moisture resistance of fabrics, films, coatings, foam, leather and multi-layer composite materials, such as clothing, quilts, sleeping bags, down jackets and other thermal clothing comfort testing Wait. It is a test equipment independently developed and produced by our company Shanghai QINSUN Precision Electromechanical Technology Co., Ltd., with high cost performance and complete after-sales service.
Applicable Standards:
GB11048, ASTM D 1518, JIS L 1096, ISO 11092
Technical parameters:
1. Test method: (1) Method A evaporative plate method, (2) Method B static plate method (3) Heat absorption and heat release test of phase change substance;
2. The size of the central test plate: length 200mm x width 200mm, thickness about 3mm. The test plate is microporous and porous made of special stainless steel. steel material powder metallurgy plate, ly simulated skin sweating effect. In an environment of 20 deg; C, the light beam with a wavelength range of 8um to 14um is irradiated vertically on the surface of the test board and reflected into a hemisphere, and the emissivity of the surface of the test board is measured to be higher than 0, 4;
3. Testable sample size: greater than 350mm times; 350mm;
4. It has a one-key preheating function, which greatly reduces the testing time and testing efficiency.
5. Sample thickness range: 0~70mm (high-precision motor-driven lifting system, quickly matched to the test of different thickness samples);

7. Thermal resistance (Rct):
(1) Test range: 0 ~ 2,000 m2 K/ W;
(2) Resolution: 0.00001m2 K/;
(3) Repeatability errorle;plusmn;2.5%;
8 Humidity resistance (Ret):
(1) Test range: 0~1000m2 Pa/W;
(2) Resolution: 0.01m2Pa/W(3) Repeatability errorle;plusmn;2.5%;
9. Airflow rate: 0.5, 1.0 , 1.5 m/s optional, plusmn;0.05 m/s adjustable;
10. Microclimate chamber requirements:
10.1 20℃plusmn;0.1℃ resolution: 0.01 ℃, 65%plusmn;2% resolution: 0.01% (thermal resistance);
10 .2 35 ℃ plusmn; 0.1 ℃ resolution: 0.01 ℃, 40% plusmn; 2% resolution: 0.01 % (moisture resistance);
11. High-precision water level automatic refill system, the error is less than 1mm;
12. Various properties of the sample can be directly measured and calculated (thermal resistance, moisture resistance, moisture permeability, moisture permeability index, heat retention, heat transfer coefficient, Cro value) without manual calculation.
