400*250*160(1000°C) Programmable High-Temperature Furnace SXF-8-10 Box-Type Resistance Furnace

The programmable high-temperature furnace, also known as the programmable box-type electric furnace or integrated programmable high-temperature furnace, features a silicon carbide inner chamber with excellent wear resistance. The furnace heats from all four sides—top, bottom, left, and right—ensuring superior temperature uniformity. The exterior is made of cold-rolled steel with a sprayed plastic finish, offering an aesthetically pleasing appearance.

The control unit utilizes a fully automatic multi-band LTDE programmable instrument with adjustable heating rates. The PID+SSR system enables synchronous and coordinated control, ensuring consistency and reproducibility for any test or experiment. It includes automatic constant temperature and time control functions, along with secondary over-temperature protection for reliable and safe operation. The control unit is integrated at the lower part of the chamber, with all electrical connections between the furnace body and the temperature controller completed before shipment. Simply connect to power to begin use. It is suitable for universities, research institutions, laboratories, and production enterprises for applications such as elemental analysis, material ashing, high-temperature sintering, small steel part quenching, annealing, tempering, as well as crystal, jewelry, and mirror coating processes.
