LFY-666 Thermal Conductivity and Pressure-Toughness and Heat Resistance Test Instrument for Protective Clothing

Main purpose/Use 
Used for testing the thermal conductivity and compression heat resistance of woven fabrics, knitted fabrics, cotton fillings, sheets and composite materials with heat insulation properties. 
Instrument Characteristics 
1. It is equipped with a constant temperature heating system that can stabilize the temperature to room temperature (400 ± 0.5) ℃. 
2. The copper calorimeter with high precision and high timeliness for temperature measurement meets the testing accuracy requirements. 
3. Equipped with an automatic system for determining the presence of copper calorimeters 
4. The dedicated data acquisition and automatic control system can display in real time the correlation between the temperature rise curve on the back of the sample, the pain curve of human tissue, and the secondary burn curve.
