Compact, lightweight benchtop furnaces For added protection, the door safety switch stops power to heating elements when door opens Thermocouple break protection cuts power to heating elements, preventing a thermocouple failure runaway condition Two open coil heating elements on chamber sides assure fast heat-up with minimum temperature gradient Thermal-efficient ceramic insulation surrounds chamber for maximum energy efficiency 0.95cm (0.38 in.) dia
port for monitoring chamber temperatures with independent measuring device at rear of chamber F47900 Models 2L (0.07 cu
ft.) of heating area F48000 Models 5.9L (0.20 cu
ft.) of heating area Includes ceramic shelf (SH480X1) that doubles furnace load capacity A1 Controller Digital single setpoint control Single display shows actual temperature or setpoint B1 Controller Digital single setpoint control with a single ramp to setpoint and a dwell Single display shows actual temperature or setpoint Furnaces with this control also use a mechanical Overtemperature Protection relay C1 Controller Digital programmable control with one stored program of eight segments Furnaces with this control also use a mechanical Overtemperature Protection relay D1 Controller Digital programmable control with four stored programs, 16 segments per program With RS-232 communications interface Furnaces with this control also use a mechanical Overtemperature Protection relay Certifications CSA approved, CE marked as indicated
