LFY-608B Resistance to Convection Heat Test Apparatus

Main purpose 
This instrument is mainly used for measuring the thermal conductivity of textiles, fire-fighting equipment and other materials. 
Instrument characteristics 
1. It can display the flame temperature, measure the temperature and show the time digitally. 
2. The burner is equipped with flame nozzles suitable for burning liquefied petroleum gas. The gas holes are distributed in an inner and outer ring pattern. The calorimeter is placed in the hole of the clamp on the sample holder and directly contacts the sample. 
3. Its main performance indicators have reached the level of similar products abroad, filling the domestic gap. The cost of this instrument is only one fifth of that of similar products abroad.
