Supplementary Report to Report on Signalling and Detection with Ultra-Violet and Infra-Red Radiation

Abstract

An investigation has been conducted to determine the feasibility of indicating the electrical output of thermocouples by means of portable equipment of a type suitable for use at sea. A moderately satisfactory system has been devised which permits the detection and indication of electromotive forces as small as thousandths of a millionth of a volt. The equipment used in the experiments is described.
