BENCHTOP MUFFLE
Model Number: F47910-26

Product Description:
� Two open coil heating elements on sides of chamber assure fast heat-up, with minimum temperature gradient.
� Maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient ceramic insulation.
� The rear of the chamber incorporates a 0.38" (0.95 cm) diameter port for monitoring chamber temperatures with independent measuring devices.
� All models shipped complete with power cord.
� Power cord supplied with all models.

Operation :
� Built-in vent port removes undesirable contaminants and
moisture; extends the life span of the element and unit.
� Four temperature controller models:
A1: Digital single set point control. A single display shows actual temperature or set point.
B1: Digital single set point control with a single ramp to set point and a dwell. A single display shows actual temperature or set point. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.
C1: Digital programmable control with one stored program of 8 segments. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.
D1: Digital programmable control with 4 stored programs, 16 segments per program. The controller also includes RS232 communications. The furnaces that use this control also utilize a mechanical Over Temperature Protection relay.
* For Calibration Verification System, see Pyrometers.

Safety :
� Door safety switch protects operator by removing power to the heating elements upon opening the door.
� Thermocouple break protection cuts power to the heating elements, prevents a thermocouple failure runaway condition.

Applications :
� Gravimetric analysis
� Sintering
� Quantitative analysis
� Heat Treating
