• Inner copper sphere of radius 100mm
• Outer copper sphere of radius 200mm
• Set of thermocouple - 4 Nos.
• Asbestos Powder is filled in between the outer sphere and inner sphere.

Control panel consisting of:

• 4 Channels Digital Temp. Indicator range: 0-300^oC
• Dimmerstat: 0-2A / 230V
• Mains ON/OFF switch
• Digital Voltmeter 0-250V
• Digital Ammeter 0-2 A
