The Hagner PR 200-X is a combined lux and UV-A meter, specially designed for control measurements when making NDT tests but naturally also very useful for other type of measurements of illuminance and UV-A radiation, in the field as well as in the laboratory. Fully compilant with ISO 3059.
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.
