Lindberg/MPH shipped a 2192°F (1200°C) three-zone tube furnace that will be utilized for technical research and development. Designed for horizontal use, the work-chamber dimensions are 36 inches long x 7 inches in diameter. The furnace, which has an insulating vestibule at each end, is equipped with a full-length hinge and a positive latch for easy observation, fast cooling, convenient placement of the process tube and overall ease of operation. The heated chamber is divided into three zones with independent thermocouples for control reference to allow adjustable profiling of end zones. In operation, the end-zone setpoints can be raised to compensate for heat losses and increase the length of the uniform temperature zone in the center of the furnace.
