THERMAL CONDUCTIVITY OF INSULATING POWDER

Product Description

The unit consists of two thin wall concentric copper spheres. The inner sphere house the heating coil. Heating coil is made up of nichrome wire wound on mica sheet. The insulating powder packed between two shells. Power supply to the heater is given through a dimmerstat & is measured by voltmeter & an ammeter. Temperature can be measured with the help of thermocouples. Four thermocouple are embedded on inner sphere and six thermocouples are embedded on outer sphere. The entire ten temperature indicator, these reading enable of insulating powder.
