Description

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
