Expansion Apparatus
Catalogue No: 1060140
Demonstrates the linear expansion of solids. Comprising two castmetal uprights joined by a pair of parallel metal support rods and supporting an expansion bar at the top. The expansion bar is tightly secured to one upright and rests beneath a friction pointer on the other upright. The pointer moves along a scale reading 0 to 90 degrees. Expansion of the bar on heating causes the pointer to move along the scale. Supplied complete with expansion bars. One each of Aluminum, brass and iron.

Joule And Watt Meter
Catalogue No: 1060950
Electrical energy consumed by a load with power is directly indicated on the front panel meter with a single selection switch. One can see either energy or power consumed by the applied load. Even we can use this instrument with data logger. A potential difference of 0-1V will generate on pulse output sockets. Max. input voltage for the meter is 24V D.C and 17V A.C with 10A max. current. Load current can be controlled by just rotating the knob fitted on the front panel indicated with load current.
