Thermal insulation performance tester for household textiles

● Multi-temperature probe collaborative detection (23 groups in total)

Testing hot plate temperature detection

Air temperature detection above the sample

Temperature detection probe for the upper surface of the sample

Reliable and advanced design: Integrated wind shield with four openable sides; designed with standard sample storage space.

● Flexible test program

Temperature stability deviation and time can be set

Duration and times of test cycle can be set

Test tolerance can be set

Test temperature can be set (meeting more standard requirements)

Standard reference samples:Can calibrate six levels of data: 0.25, 0.50, 0.75, 1.00, 1.25, and 1.50, ensuring more accurate test results

● Technical Parameters

This precision equipment requires calibration, and under appropriate environmental condition control, the test accuracy can reach 1%.

Electric furnace and guard plate temperature: 33℃±0.1℃

The temperature variation between the measuring surface and the guard hot plate is less than 0.1℃

All heaters are equipped with overheat protection

Heat output: 5-30W, external current: less than 20mW

Main electric heating plate: 1.0m×0.68m

Thermal control area (including guard plate): 1.31m×0.91m

Equipped with 3 standard samples (0.25 m²·K/W, 0.5 m²·K/W, 0.75 m²·K/W)

A stable DC power supply provides voltage and current for the electric heating plate power, with continuous independent measurement;

The computer interface includes a self-calibration facility to ensure a voltage measurement accuracy of 0.1%. The software implements the process specified in Section 4 of Appendix D in BS5335-2:1991; other programs can be customized according to actual needs;

Records the system temperature throughout the measurement cycle for verification;

Equipped with a function to judge the stability of measured data, with configurable judgment parameters;

Enables on-site reporting of results and test progress;

The instrument uses a six-point probe to measure the heat flux in the electric heating plate area;

Software can be upgraded via the Internet;

Complies with CE electrical safety regulations and EMC (Electromagnetic Compatibility) standards.
