Figure 22 (cont). Richter thermometers constructed by the German instrumentmaker Carl Richter following the suggestions of Fridtjof Nansen. Two of these were received in March 1901 and sent to Roald Amundsen for testing in Arcticwaters. Although not a revolutionary design, this instrument had many improvements that were followed for tens of years. (Image credit: Oceanographic Museum of Monaco | Y. Berard)
