An apparatus is described in which constant pressure is maintained as gas is absorbed or evolved by changing that volume of a threaded rod which is inside the apparatus. The change in volume of the gas is then equal to the change in volume of the rod inside the apparatus. Use of an escapement to turn the screw through constant-volume increments provides a simple method of automation.
