Gunther Expansion Apparatus
Gunther Expansion Apparatus
With Altay’s Thermal Expansion Apparatus, students can accurately and easily investigate the expansion of metals with increasing temperature.
Ideal apparatus for the determination of the coefficient of linear expansion of a solid.
The apparatus comprises of a double metal plastic jacket containing the rods which will be raised to a temperature of 100°C.
A micrometer gauge is mounted at one end and will show any expansion of the rods to 0.005mm accuracy.
We make temperature measurement simple, yet accurate.
We measure directly the temperature of each tube, so that we do not have to wait for steam or water moving through the tubes.
A digital multimeter can be use to directly measure the Resistance-to-temperature ratio.
Comes complete with one brass, one aluminium and one iron rod, length 50cm approx, mounted in the double jacket.
Equipment Needed:
Filtering Flask – Code 1331
Bunsen burner with accessories – Code 5511.00 or similar
Digital multimeter – Code 2275.10 or similar device to detect short circuits
