For the measurement of actual (total gaseous) pressure. Circular gauge, overall diameter 106mm, depth 40mm. The dial reads 0 to 3.4 x 105 Pa actual (total) pressure and the case has a clear perspex back so that the working parts may be seen. A tubule, 8mm diameter, provides connection to the system under investigation. The gauge is mounted on a heavy base 102 x 102 x 25mm, with rubber feet. Overall height: 220mm.

D. Charles Law Apparatus
A capillary tube, sealed at one end with a calibrated scale in cm and mm. In use a mercury bead is inserted in the tube which can then be heated in a water bath to investigate temperature/volume for the enclosed air column. Readings are taken directly from the tube so there are none of the problems associated with attached rulers or elastic bands. Full instructions included. Supplied without mercury.
