Hemovitameter

The Hemovitameter is an electro-mechanical device, designed by H. D. Niblack and sold through Dr. Niblack Laboratories of Denver, Colorado, that was sold as a medical diagnostic apparatus, consisting of a wooden console housing "a radionic-type electrical device with a large central instrument panel containing several dozen switches, dials, meters, rheostats, and electrode connectors as well as two smaller side panels and a draw-type detector plate." Similarly to devices like the Oscillotron, the subject would be connected to the electrodes while the operator used the console to ostensibly diagnose what, if any, diseases or other ailments afflict the subject.
