UV irradiance meter

The factory calibration certificate documents the intended measurement functionality of the calibration item. Calibration is performed by comparison with test material that is subject to test material controlling in accordance with EN ISO 9001. Traceability of test material is ensured by calibration by the Physikalisch-Technische Bundesanstalt (PTB, National Metrology Institute of Germany).

Calibration (new as well as recalibration) of an irradiance meter is performed with a reference irradiance meter by direct comparison (substitution method) of the measured values of the device under test with those of the reference device. The emission spectrum of the UV source is checked during the measurements using a spectroradiometer. The various calibration points are set by changing the distance between the reference standard and the radiation source.

The applied calibration procedure meets the requirements of

  • EN ISO 3059:2013-03 Section 8
  • CIE 220:2016
  • ASTM E2297:2015

The factory calibration certificate documents the metrological traceability to national standards for the representation of units in accordance with the International System of Units (SI).

The following measuring devices can be calibrated (other measuring devices on request):

  • Mavomaster LUX / UVA
  • Kombi UV-LUX
  • UV-2000
  • UV-2500 II
  • J-221

The following test report can be delivered:

  • Test report UV irradiance meter Mavomaster LUX / UVA
  • Test report UV irradiance meter Kombi UV-LUX
  • Test report UV Irradiance Meter UV 2500 II
  • Test report UV irradiance meter J-221
  • DAkkS Calibration UV Irradiance Meter Kombi UV-LUX

Illuminance meter

Factory calibration (new as well as recalibration) of an illuminance meter is performed with a reference illuminance meter by direct comparison (substitution procedure) of the measured values of the meter under test with those of the reference meter. The supply current of the A-source is adjusted and stabilised with a power supply. The different calibration points are adjusted by changing the distance between reference standard and A-source.

The applied calibration procedure meets the requirements of

  • EN ISO 3059:2013-03 section 8
  • ASTM E2297:2015
  • BS 667:2005

The factory calibration certificate documents the metrological traceability to national standards for the representation of units in accordance with the International System of Units (SI).
