Conductivity Apparatus Lee's And Charlton's

Conductivity Apparatus Lee's and Charlton's :

For determining the relative conductivity of thin layers of material consisting of cylindrical slab of Brass 11 cms. in diameter and 12mm. thick. On theis rests a 45mm deep hollow cylinder brass N. P. of same diameter with inlet and outlet tubes for Steam. Both the cylinders have radial holes for insertion of thermometers. The material under test is placed between two cylinders. The apparatus is suspended by strings attached to the lower cylinder without thermometer. Complete with one each specimen disc of glass, & ebonite/hylam but thermometer
