Main purpose:
It is used to measure the thermal resistance and moisture resistance of various textile products and textile fabrics, films, coatings, foam, leather and composite materials used to make these products under steady state conditions.
Instrument features:
1. Imported high-precision temperature sensor;
2. Integrated design of high-precision constant temperature and humidity chamber and instrument;
3. DSP microcomputer control and data processor;
4. Professional analysis software can directly measure and calculate the thermal resistance, moisture resistance, moisture permeability, moisture permeability index, thermal insulation, thermal conductivity, Kroos value, etc. of the sample;
5. Digital temperature sensor, real-time, fast and dynamic collection of temperature and humidity data, multi-point independent calibration;
6. National patented technology simulation test bench for human skin structure;
7. Imported motor and lifting system, capable of digital height setting, quickly compatible with testing of samples of different thicknesses;
8. Equipped with patented technology, the automatic water supply system provides high-precision water level replenishment with an error of less than 1 millimeter.
9. The whole machine has undergone special humanized testing, which is convenient, concise, and highly operable.
