Lee's And Charlton's Apparatus Manufacturer,Supplier and Exporter in India
Product Code : ILS-H-10928
Indian Lab Suppliers supplies the Lee's And Charlton's Apparatus (Product ID: 10928) as part of its heat and thermal physics range. Lee's and Charlton's apparatus measures the thermal conductivity of a thin layer of a poor conductor.
Quick Answer
The specimen is sandwiched between a brass steam chest, 4.5 cm deep with steam inlet and outlet, and a brass slab 11 cm across and 10.5 mm thick. Each has a radial hole for a thermometer, and the slab hangs by three strings from an annular ring on a heavy retort stand. At steady state, the heat flowing through the specimen equals the heat the slab loses, found from its cooling rate at the steady temperature. An iron slab of the same size is also available. Thermometers are not supplied; handle steam lines with care.
