An Improved High-Precision Calibration Procedure. For Reference Standard Hydrometers. Horace A. Bowman and William H. Gallagher. Institute for Basic Standards, National Bureau of Standards, Washington, D.C. 20234. (June 24, 1969) This paper describes a method of calibrating hydrometers which. although no more accurate. that the technique used heretofore at the National Bureau of Sta ndards, reduces calibration time.
