Mobile Erythemal Radiometer

The XD-45-ERYC-4 irradiance detector is specially designed for the measurement of the Erythemal effective UV radiation in tanning equipment. Gigahertz-Optik’s X14 optometer enables health and safety executives to do on-site measurements at the tanning salon conforming to published safety standards.

Measurement of the UV-C Limit Value

The relevant German UVSV (Verordnung zum Schutz vor schädlichen Wirkungen künstlicher ultravioletter Strahlung) specifies the limit values for Erythemal effective irradiance at 0.3 W/m² within the wavelength range from 250 nm to 400 nm. From 200 nm to 280 nm the irradiance should not exceed 0.003 W/m². The XD-45-ERYC-4 detector is set-up with a third UV-C sensor to measure any existing UV-C radiation at 254 nm with low uncertainty.

Cosine Corrected Field of View

The angular response of the XD-45-ERYC-4 detector is cosine corrected.

Traceable Calibration

Calibration of the detector responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.
