The 2,5-10 Heating Furnace is a compact electric muffle or box-type resistance furnace designed for high-temperature applications in laboratories, materials testing, ceramics, small metal heat treatment, and other industrial/research settings. The model “2,5-10” typically denotes a furnace with a 2.5 kW power rating and an internal usable chamber volume of about 2 litres, with internal dimensions around 200 × 120 × 80 mm. These furnaces are capable of reaching maximum temperatures of ≈1000 °C. They are commonly built with heavy insulation, robust steel exteriors, precise temperature control (PID controllers), and safety features suited for frequent use.
