The Scandico Systems PR 200-X is a combined lux and UV-A meter, specially designed for control measurements when making NDT tests and other types of measurements of illuminance and UV-A radiation, in the field as well as in the laboratory. The instrument is compact, ergonomic and easy to use. The two detectors are cosine corrected for angular incidence of light and the illuminance detector is carefully filtered to the spectral sensitivity of the human eye in accordance with the CIE standard. The UV-A detector measures radiation between 315 – 380 nm with a peak at 355 nm. The light sensitive device used in the detectors are very stable long life silicon diodes which results in high reliability and increases recalibration intervals.
