Thermal Resistance YG(B)606N

[Instrument Name]：Fabric Thermal Resistance Tester

[Scope of Application]: It is used to measure the thermal resistance of textiles—defined as the dry heat flux passing through a specified area under a steady temperature gradient—using the sweating guarded-hotplate method.

[Relevant Standards]: GB/T 11048, ISO 11092:1993, ASTM D1518, ASTM F1868-02, JIS L1096-2010, etc.

[Instrument Features]:

1. Integrated design with a compact, robust structure ensures reliable instrument operation.

2. Utilizes microcomputer control and data processing; professional analysis software directly measures and calculates performance parameters such as thermal resistance, thermal insulation rate, thermal conductivity, and Clo value.

3. Equipped with a high-performance computer; test results are output as printed test reports.

4. Rapid, real-time dynamic acquisition of temperature and humidity data, combined with independent multi-point calibration, ensures the accuracy and authenticity of test results.

5. Manual platform positioning system adjusts the testing platform to the appropriate location based on sample thickness.

6. Designed with a user-friendly approach to ensure convenient, simple, and highly operable testing procedures.

7. Airflow stabilization system ensures a continuously adjustable wind speed (0–4 m/s) that is uniform and stable, meeting the requirements of various testing standards.
