Product number: H112A

A small-scale accessory that allows experimental investigation of linear heat conduction and the measurement of the thermal conductivity of various solid conductors and insulators. 

An insulated, 25mm diameter brass heated section and cooling section that may be either clamped together, or assembled with one of four insulated intermediate sections or test specimens between the interfaces.

The hot end uses a nominal 75W heater (operating at 240v maximum), which is fitted with a high temperature limit switch. The power supplied to the heater is controlled and measured by the H112, Heat Transfer Service Unit.

The cold section is of identical dimensions to the hot end and is water-cooled. Both the heated and cooled ends
are each fitted with three thermocouples at 15mm intervals to measure the temperature gradients along the bars.

All eight thermocouples plug directly into the H112, Heat Transfer Service Unit and temperatures are displayed on its digital panel meter.
