Laboratory Chamber Furnace
High-precision laboratory electric furnaces with fibre-insulated chambers made of high-quality materials.
The models of these low-temperature ovens are designed for the heat treatment of materials up to 300°C.
The forced air covection allows an even temperature distribution and ensures optimal results.
The oven is suitable for use in scientific laboratories, educational institutions, medicine and industry.
Applications
- Drying
- Heating
- Thermal testing and aging
- Similar applications in an environment with natural airflow.
