The Apparatus consists of three concentric pipes mounted onsuitable stand. The space between innermost and the middle pipeis fixed with a lagging material and the space between the middleand the outer most is filled with and other lagging material. Thelagged pipe is heated with a cartridge heater inserted at the axlelength of the pipe. Voltmeter and ammeter on the panel canmeasure the input to the heater. The intermediate temperatures canbe measured by the thermocouples attached at the surfaces of thepipe. Thus the resultant conductivity of the materials can be foundout.

This is an analog tachometer which can measure RPM of a rotating shaft or peripheral speed without requiring any special stopwatch. Easy to use with excellent accuracy.

As soon as a suitable contact tip attached to the meter is pressed lightly to the rotating shaft center, spindle is turned. When the button on the top is pressed and released, the spring is charged, the clock operates, and the pointers revolve, automatically stopping at certain scale points to show RPM of the measured machine.

Concave rubber contact tip, 1 Convex rubber contact tip, 1 Wheel(pulley) for peripheral speed measuring
