A NEW SPECTROGRAPH TESTING TECHNIQUE, ESTABLISHED AT PEARL HARBOR NAVY YARD
WESLEY HASKINS HAMMOND · Journal of the American Society of Naval Engineers · 1940
The Industrial Department of the Pearl Harbor Navy Yard has recently installed a grating spectrograph in the general testing laboratory to be used in increasing the technical efficiency of ship overhaul work. The Pearl Harbor spectrograph is of a relatively new type to be manufactured for general industrial analysis. There are features in its installation of original design. The uses to which such a piece of equipment may be put in a purely repair and maintenance yard may not be self‐apparent. Therefore, its description will be of interest as an adjunct to the control and inspection of materials.
