dc.descriptionThis document summarizes the results of testing and calibration of the airplane thermometer made by Hartmann & Braun, Frankfort on the Main, Germany, which is of the electric resistance type. It consists of two resistance elements and an ohmmeter indicator, from which the temperature of either element can be read by throwing a switch. This type of thermometer will probably be found valuable in replacing liquid and vapor types of thermometers.en_US
