Sweating Guarded Hotplate
Thermal resistance wet resistance tester

Testing Standards:

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

The Thermal resistance wet resistance tester simulates the heat and mass transfer processes which occur next to human skin. Measurement of thermal resistance and water vapor resistance under steady state conditions of a range of products of fabrics, films, coatings, foams, and leathers, including multi-layer assemblies, for use in clothing systems.

Product Information
In the standard testing environment, heat the fixed aluminum or copper to a specified temperature, then test the heating power under the stable temperature. Similarly, place the cloth specimen on the copper or aluminum plate and test the power in the same condition. According to the power difference of the twice and area size of the tested plate, thermal resistance and water vapor resistance of test samples can be calibrated.

Professional Technology
1. The world's first independent design concept, integrated design of control systems and automatic water supply system, with the standard Climate Chamber for optional.
2. Automatic water supply, Automatic drain system, Strong feed water system (In the Evaporative Resistance test mode, water uniformly wets test plate faster).
3. High-precision automatic mobile system for the test platform, enter the thickness of the test sample, the test platform to move to the corresponding position.
4. According to the thickness of the sample, the machine could automatically adjust the PID control parameters, then quickly reach to the required test conditions.
5. The patented Air velocity parallel stabilization system, makes the Air velocity homogeneous and stable, more stable of the test results.
6. Air velocity continuously adjustable from 0~2m/s to meet any Thermal and Evaporative resistance testing standards.
7. Guard ring width of 127mm, to ensure that whole heat is just passed through the test sample than other way.
8. LED soft lighting system.
9. Standard USB communication, optional wireless wifi communication, to make more convenient connection.
10. Machine stainless steel shell to ensure the life of the machine more than 20 years.
11. Friendly and convenient testing software, test software to configure variety of test standard and user-friendly.
