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.
They are suitable for processes such as drying, heating, thermal testing, aging and similar applications in an environment with natural airflow. 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.
