LFY-608B convection heat resistance test device
This instrument is mainly used to determine the thermal conductivity of textiles, fire-fighting supplies and other materials.
The main purpose
This instrument is mainly used to determine the thermal conductivity of textiles, fire-fighting supplies and other materials.
Instrument characteristics
1. The flame temperature, measuring temperature and time can be displayed digitally.
2. The burner adopts a flame nozzle suitable for burning liquefied petroleum gas. The air holes are distributed in an inner and outer ring. The calorimeter is placed in the hole of the splint on the sample rack and directly contacts the sample.
3. Its main performance indicators have reached the level of similar foreign products, filling the domestic gap, and the cost of the instrument is only one-fifth of that of similar foreign products.

(1) Heat source: liquefied petroleum gas
(2) Heat flux density: greater than 40KW/m2
(3) Measuring temperature range: 20℃～200℃
(4) Timing range: 0～100s
(5) Sample size: 140mm×140mm
(6) The diameter of the calorimeter: Φ40mm
(7) Power supply: AC 220V 50Hz 1.5kW.
