Vintage Eimer & Amend OSMOSCOPE Wooden Box Odor Smelling Detector tool. Pretty good condition. No clue if it works or not. It extends just fine.Wooden box is original but most of the lip where the lid slides on is broken off.
The osmoscope measured the intensity of odors using an exponential scale in powers of two. The process works by dilution of the odor by air. This tool was created around 1938, and works by diluting the odor in the air. The device is then inserted into a test tube, and holes in the side of the tube allow air to enter. A sliding jacket is then drawn up the osmoscope to progressively cover the tube and holes in order to create a more intense odor.
The application of the osmoscope to psychology is to test olfactory perception. Once the odor becomes increasingly stronger due to the sliding jacket, the two probes at the end of the osmoscope would be inserted into the nose of a human subject. A small amount of gas would be rapidly passed directly into the olfactory regions, allowing the subject to experience and assess the odor for their experimenter.
