Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a copper sphere in which a mica heater is fitted. The sphere is surrounded by another bigger sphere and between the two spheres, the test insulating powder is filled. Heat of the heater radically flows outwards in all directions through powder. The temperatures of spheres i.e. temperatures across the powder are measured. By knowing the input to the heater conductivity of the powder can be determined.
The unit is supplied filled with asbestos powder, but any other can be tested in the unit.
