Sweating Guarded Hotplate

G259A Sweating Guarded Hotplate is the most professional, most advanced  Thermal and Evaporative Resistance test instrument, simulate the human skin test  plate, Auto matic water supply system, Wind speed stabilization system, test  unit and Climate Chamber completely separated design, Aluminum alloy shell to  ensure that won't rust.

Sweating Guarded Hotplate tester to determine the thermal and evaporative  resistance of clothing materials, under standard test environment, heat the  fixed aluminum or copper. Keep them to maintain a fixed temperature and heating  power. At the same time, after covering the aluminum or copper with test fabric,  do the power test under the same situation, and test the size of test platen  with the power difference. And then determine the thermal or dampness of the  test sample.

Applications

Measurement of the thermal resistance and the evaporative resistance, under  steady-state conditions, of fabrics, films, coatings, foams, and The  quilt,including multi-layer assemblies, for use in Clothing production.

Technical Parameters

Test Procedures

Sample Preconditioning: Place specimens under standard atmospheric conditions  for humidity conditioning to ensure material stability.

Sample Cutting: Use the dedicated template to cut “L”-shaped or square  specimens of specified dimensions (as prompted by the software).

Sample Placement: Lay the specimen flat on the test platform, ensuring no  wrinkles and that the grain direction complies with standard requirements.

Test Initiation: Enter sample information in the software interface and click  “Start.” The instrument will sequentially perform compression, bending, surface  friction, and heat exchange tests.

Data Generation: Upon test completion, the system automatically calculates  various tactile metrics (e.g., Smoothness, Softness, Warmth).

Result Export: Generate objective tactile radar chart reports for convenient  data storage or cross-team sharing.

Maintenance Information

Sensor Protection: Pressure and heat flux sensors are highly precise. Never  press directly with fingers or touch sensing surfaces with sharp objects.

Cleaning and Maintenance: After each test, use an air pump or soft, lint-free  cloth to remove fiber debris and dust from the test platform surface.

Regular Calibration: It is recommended to calibrate pressure and heat flow  every six months using the included standard blocks to ensure data accuracy.

Software Updates: Regularly check for driver and algorithm updates to obtain  the latest tactile rating models.
