Electric heating Furnace

Electric furnaces generate heat by passing an electric current through a resistance wire, converting electrical energy into thermal energy. They are used for heating, ashing, melting, and other treatments of laboratory samples, and are suitable for high-temperature testing and pretreatment of materials.
Selection
When selecting an electric furnace, consider matching the heating temperature range with sample requirements, pay attention to heating rate and temperature control accuracy, determine the furnace capacity based on sample container dimensions, check insulation and safety protection features, and choose durable heating elements according to usage frequency.
