Products Description
The hydrogen atmosphere box furnace adds an extra hydrogen ignition safety device to the basic atmosphere furnace, allowing it to meet the explosion-proof and flame-proof requirements of the place of use. It is equipped with automatic detection of hydrogen and can be filled with hydrogen atmosphere. The hydrogen atmosphere can enable heat treatment under relatively reducing conditions to avoid oxygen contamination of the work-piece to be heat treated. Safety, efficiency, diversity, flexibility.
Feature
1. Multi-purpose atmosphere furnace filling (including hydrogen)
2. The maximum temperature can reach 1750℃ (non-hydrogen environment, hydrogen environment ≤1450℃)
3. Precisely controlled temperature controller CE, UL certified
4. Available from 1L to 36L
