Catalog of Oceanographic Equipment Contained in the Collection of the Museum of Oceanography of Monaco. 1. "Photometers 2. Current Measuring Devices" by Christian Carpine. Bulletin de l'Institute Oceanographique , Vol. 73, No. 1437. 1987.

Figure 1. H. Fol and E. Sarasin Photometers. 1. 1884 model. 2. and 3. 1885 model. 4. and 5. 1886 model as published in Fol and Sarasin, 1887. Photometers are instruments to measure light. They are used to study how far light penetrates into the water, sometimes the color of the water, and, also in modern instruments, bioluminescence.

Figure 2. H. Fol and E. Sarasin photometer, 1884 model. Left: device closed. Right: Device opened. This instrument was used in 1885 to study the penetration of light in Lake Leman and after that in the Mediterranean. It was tried off Cape Ferrat, France, in between 200 and 400 meters water depth.

Figure 3. H. Fol and E. Sarasin photometer, 1885 model. From top to bottom - Device closed; device open; the surface float. This model was designed to fix the weak point of the preceding model that was not able to execute a sole measurement at a given depth.

Figure 4. H. Fol and E. Sarasin photometer, 1886 model. This instrument was tested at Villefranche-sur-Mer on board Fol's yacht, the AMPHIASTER. The results were not published.

Figure 5. P. Regnard's combination photometer and photometric recording device. Invented by Paul Regnard in 1888 for measuring the intensity and duration of lig light with increasing depth. It was used by Prince Albert aboard a steam tug off Funchal at depths of 20, 30, and 40 meters. The balloon pressure device was not part of the original instrument but added afterwards.

Figure 6. P. Regnard hydrochloric acid tube designed by Paul Regnard about 1889 to study the chemical action of light in oceanic waters.

Figure 7. E. von Petersen's photometer. Left: device before opening. Middle: device during exposure. Right: device after closing. This device was invented in 1886 by Eugen von Petersen, an engineer at the Naples zoological station. The design follows the specifications of Carl Chun. The first test of this ins trument was by Carl Chun off Capri in 250 meters water depth.

Figure 8. L. Linsbauer's photometer. Left: a picture of the unit. Right: a picture of the internal photometer mechanism. This instrument was invented by Ludwig Linsbauer for use in fresh water. It was used in Lake Traunsee in the northern part of Austria in 1904 at small depths.
