Sweating Guarded Hotplate

Sweating Guarded Hotplate

Compliant with standards:

GB/T 11048, ISO 11092, ASTM F1868, ASTM D1518, JIS L1096

Applicable scope:

By simulating the process of heat and water vapor generated by human skin penetrating fabrics, the thermal and moisture resistance values of various materials are tested in a stable temperature and humidity environment. It can be used to test the thermal resistance and moisture resistance of fabrics, films, coatings, foam, leather and multi-layer composite materials, such as clothing, quilts, warm clothing, and textile fabrics for human comfort.

Testing principle:

In a standard testing environment, heat a fixed aluminum or copper plate to maintain a fixed temperature and test the heating power. Similarly, after covering the test fabric on the copper or aluminum plate, test the power under the same conditions, based on the power difference between the two and the size of the test disk area. You can calibrate the thermal or wet resistance of the test sample (by adding water for testing).

Technical features:

1. Independent design concept, integrated design of control system and automatic water supply system, users can choose to equip different environmental experimental boxes.

2. Automatic water supply, automatic drainage system, and strong water adding system (during wet resistance testing, the heating plate can penetrate water more quickly).

3. High precision automatic platform movement system, input the thickness of the test sample, and move the test platform to the corresponding position.

4. Quickly reach a stable testing state, and the machine automatically adjusts PID control parameters based on the sample thickness, which can quickly reach the testing conditions.

5. The wind speed parallel stability system ensures uniform and stable wind speed, making the test results more stable.

6. The wind speed can be continuously adjusted from 0 to 2m/s, which can meet any wet resistance, thermal resistance, and insulation performance testing standards.

7. The width of the thermal protection ring is 127mm, ensuring that heat is only transferred from the test sample.

8. LED soft lighting system.

9. Standard USB communication and optional wireless wifi communication make the connection more convenient.

10. The stainless steel casing of the entire machine ensures a service life of more than 20 years.

11. Friendly and convenient testing software, with various testing standards configured for user convenience
