Hagner - Model S5 -Universal Photometer
FromB. Hagner AB
The Hagner S5 Universal Photometer is the fifth generation of Hagner™s Universal Photometers. (Actually it is the sixth but the first one was built with cadmium sulphide diods and is therefore not included in the S-serie.). The S5 is though the first digital version. As its precursors it of course measures luminance as well as illuminance but it can also save readings in its memory, directly present correct readings on the display when using any of Hagner™s special detectors and be set for metric as well as imperial units.
