Intercomparisons VioSpor® versus Spectroradiometers
The high quality of the VioSpor® UV-dosimetry system has been demonstrated by several blind test intercomparisons on national and international levels [see literature]. The standard deviation of ± 10% (MED determined with VioSpor® and spectroradiometer) to the spectroradiometer values underlines that VioSpor® is a highly precise broadband dosimeter useable for applications where a high measurement quality is demanded. Important references of the UV-measurement system VioSpor® (national and international measurent intercomparisons and measurement accuracy):

Validation of the system at sun light and monochromatic radiation (blind-tests, linearity, absolute accuracy at high and low radiation angles of the sun, VioSpor®- accuracy appr. +/-12%! Testing (blind test) of the VioSpor® - response at 303, 312 und 365(!) nm)
Intercomparision of various systems in an national intercomparison (double monochromators) 1997 in Garmisch-Partenkirchen (Germany), Poster together with Seckmeyer et al. on the ECUV-meeting 1998 in Helsinki (blind-tests). VioSpor®- accuracy: appr. +/-10%!
Intercomparison of the system at European level (1998):
Publication planned (blind-tests). VioSpor® - accuracy: appr. +/- 7 %!
In addition VioSpor® was used in 1998 in comparision to a RB-meter of the WMO and to other fresch calibrated RB-meters (of our costumers) blind-tests. VioSpor® - accuracy appr. +/- 10 bis 15 %!
Additionally we have done a lot of in-vivo-comparisons with various UV-radiation sources.
For understanding of the measurement accuracy:
The report The 1997 Status of Solar UV Spectroradiometry in Germany: Results from the National Intercomparison of UV spectroradiometers (Band 55-1998, Seite 5) in Garmisch-Partenkirchen (Germany) describes as measurement uncertainties for the best German spectroradiometers a values +/-15%!
