Lot of a microscope and photovolt meter. The photovolt meter was made by the Photovolt Corporation and was used to measure the intensity of light. Meter comes in a wooden case and the meter can move but it is unknown how accurate it is. Microscope does not have any maker marks but has likely come from a high school. Microscope still works but the wheel is stiff and can be hard to move at times. Overall, both pieces are in good condition and are from the 1950's era. See photos.
