Title | Paper, 'On a thermopile and galvanometer combined' by George Forbes |
Date | 1886 |
Description | Forbes writes: 'The author has lately made use of a special form of thermopile and galvanometer combined, which is very sensitive for the measurement of radiation. The apparatus is especially suitable for use as a line-thermopile. The first experiments were made with two half tubes, one of antimony the other of bismuth, soldered together so as to make a short tube about 2 cm. external diameter, the walls being 2 mm. thick, and the length of tube about 2 or 2½ cm.'
