Calorimetric resistance thermometers and the transition temperature of sodium sulphate
A technical report by H. C. Dickinson and E. F. Mueller, issued by the National Bureau of Standards in 1907 for physicists and instrument makers working on precision thermometry and calorimetry. Line engravings show sectioned thermometer bulbs and calorimeter vessels with hatched walls and letter keys, a bridge circuit diagram with coiled resistances and dial switches, plus a halftone of a laboratory bench.
