Spirometer, Collins, circa 1965, close up
A counter-weighted water seal spirometer. The main pen was attached to the counter-weight and drew a volume-time curve on graph paper attached to the kymograph drum. The secondary pen was attached to a mechanical integrator and was used for MVV tests. Photo found at http://www.pemed.com/techantq/tantique.htm
