Product Description

Description of Thermal Conductivity Apparatus:

The apparatus consists of a vertical stack of specimens clamped between an electrically heated source at the top and a water cooled base, all contained within a Dewar vessel and furnished with a radiation shield and anti convection baffle. The specimens are fitted with very small thermocouples at known distances apart and connected via a selector switch to a digital temperature readout. The heating current is supplied from a variable voltage power pack and displayed on a digital ammeter. The water cooled base is designed as a calorimeter to measure the heat flow and fitted with very accurate thermometers in the water circuit. Cooling water is supplied from the constant head water tank mounted above the Dewar vessel.

Experimental Capability of Thermal Conductivity Apparatus:

  • To demonstrate that heat flow is directly proportional to temperature differences between specimen faces  
  • To demonstrate that heat flow is directly proportional to cross sectional area  
  • To derive the thermal conductivity of materials of high thermal conductance
  • To determine the thermal conductivity of insulation materials

Specification of Thermal Conductivity Apparatus:

To comprise electrically heated self-clamping specimen stack, calorimeter base, Dewar vessel and cooling water supply mounted on instrument case. Front panel to carry a thermocouple selector switch, variable voltage power supply and digital ammeter and temperature meters. Two high accuracy thermometers, four NiCr/NiAl thermocouples and six various metal specimens comprising of mild steel, copper aluminium and stainless steel to complete the unit.
