Product Features (Fire Assay Furnace)
- Designed specifically for fire assay analysis, 12 samples per batch
This fire test furnace is specifically designed for fire assay analysis in the field of exploration geochemistry. It is used to analyze the precious metal content in samples such as cores, rocks, river sediments, soil, glacial debris, and vegetation. The furnace chamber dimensions are 430mm (depth) × 250mm (width) × 200mm (height), and it can melt 12 samples at a time, meeting the needs of batch sample analysis.

- Electric and pneumatic top-opening door, foot switch control
The furnace door uses a combination of electric and pneumatic top-opening mechanism, equipped with a foot switch to control the opening and closing height. Operators can focus on handling samples with both hands without having to manually lift the door, thus avoiding the risk of burns from high temperatures.
- 7-inch touchscreen for program setting and data recording
Equipped with a 7-inch touchscreen, it allows for functions such as setting the heating program, viewing historical curves, exporting data reports, and real-time power display. The touchscreen operation is intuitive, process parameter settings are convenient, and data recording is complete.
- U-shaped silicon carbide rod heating, arranged around the perimeter
The heating element uses U-shaped silicon carbide rods of equal diameter, vertically installed on the inner wall of the furnace. The silicon carbide rods are made primarily of high-purity α-SiC, offering advantages such as rapid heating, high thermal efficiency, long lifespan, resistance to deformation at high temperatures, and ease of installation, operation, and maintenance. Temperatures can reach 1500℃.
