Product Description

The ‘Swarg Systems & Instruments’ apparatus consists of a slab assembly. The main heater and a radial guard heater are sandwiched between copper plates. The specimen in the form of slabs of equal thickness are placed on either sides of heaters and cooling plates through which water is circulated are on the other sides of specimen. Radial guard heaters ensures all heat of main heater passes axially through the specimens, which is collected by cooling plates. By knowing the temperatures and heat input, thermal conductivity of specimen can be calculated. The test set up is enclosed in an enclosure with insulation inside to reduce radiation losses and to provide undisturbed surroundings. The design of the apparatus is similar to that recommended in INDIAN Standard, the difference is in sizes.
