Used WATKINS-JOHNSON QR #114979 for sale

WATKINS-JOHNSON QR is an industrial-grade oven/furnace equipment designed for annealing, sintering and brazing of a range of ceramic, metal and composite components. The furnace is capable of achieving temperatures up to 1100°C, with highly accurate and repeatable heating, cooling and ventilating profiles. The advanced temperature control system, including a PROGRAMMABLE PID CONTROLLER, provides a high degree of accuracy, temperature uniformity and rapid response to temperature demands. The unit features three temperature zones (front, center and rear) and is accessible from both the top and bottom of the unit. The individual zones can be set to different temperatures and enable the user to create a range of heat profiles for annealing, sintering or brazing. QR is constructed from precision-cast aluminum and is shielded with a removable stainless interior that increases thermal insulation and accelerates heating and cooling. On the exterior, the furnace casing is made from temperature-resistant lightweight aluminum alloy, with a firebrick lining to further insulate the machine from ambient temperatures and provide maximum thermal efficiency. WATKINS-JOHNSON QR also features advanced safety features, including a high-limit safety switch, a thermocouple reset circuit and low-level cooling. These features provide optimum fire protection, and the OVERLOAD PROTECTION circuit shuts off the tool in the event of an over-temperature situation. The unit is also equipped with a range of additional features and applications, including a WATKINS-JOHNSON Precision Timer, which enables the user to set accurate, repeatable exposures, and a WATKINS-JOHNSON Hi-Temp Sensor for monitoring temperatures for extended durations. QR is an advanced oven/furnance asset ideal for a variety of industrial-grade applications, from annealing and sintering to brazing. It provides reliable and repeatable heating, cooling and ventilation profiles and is protected from external temperatures with advanced safety features and a lightweight insulated aluminum exterior. Additionally, with its precision temperature control model, including the PROGRAMMABLE PID CONTROLLER, and additional features such as WATKINS-JOHNSON Precision Timer and WATKINS-JOHNSON Hi-Temp Sensor, the equipment ensures accurate, efficient and consistently reliable results.
