BENCH TOP HIGH TEMPERATURE MUFFLE FURNACES Bench top High Temperature Muffles Furnaces offer heating area and include a ceramic shelf to double furnace load capacity. Highly thermal-efficient ceramic insulation surrounding the chamber achieves maximum energy efficiency. Open coil heating elements on both sides of chamber enable rapid heating with minimal temperature gradient of 1400째C. A builtin venting system removes contaminants and moisture. Door safety switch provides operator protection by cutting power to heating elements when door is opened. It features a digital programmable control and is available with a single stored program of eight segments. All furnaces utilize a mechanical Over Temperature Protection relay.

These furnaces use open coil heating elements on both sides of the heating chamber to allow fast heating with minimal temperature gradient. This energy efficiency is enhanced through the use of high thermal-efficient ceramic insulation surrounding the chamber. The freefloating, ceramic fibre door includes a chamber plug that prevents heat loss around the door by totally sealing when the springloaded door is closed.

Temperature is controlled via PID automatic control via SCR (Silicon Controlled Rectifier) power control, e.g. current limiting phase angle fired the resistor with 30 steps programmable. The digital single set point control features a single ramp to set point and a TECHNOCRACY PVT. LTD.

dwell, again with a single display but also with a mechanical Over Temperature Protection relay. The digital programmable control features 1 stored program with 8 segments, along with RS232 communications. This microprocessor control features adjustable overtemperature protection, sensor-break protection, and digital readout of both set point and muffle furnace temperature.

A built-in venting system allows easy removal of undesirable contamination and moisture, making this muffle furnace especially suitable for use with sensitive microelectronic components. A port allows you to purge the chamber with nitrogen or other special atmospheres, thereby enhancing moisture and contamination control; this port can also be used for independent temperature monitoring.

The interior chamber features built-in racks that allow adjustable positioning of a ceramic shelf (included), which effectively doubles the working area. It comes with complete with on/off switch, thermocouple and grounded three-wire cord and plug.
