Order part number: ILT1400 (meter), SEL240/NS254/TD (detector)

Applications:  This detector has a narrow bandwidth with a center wavelength at 254 nm facilitating the measurement of germicidal effectiveness at 254 nm from medium-pressure mercury lamps, xenon arc lamps, mercury arc, or mercury-xenon arc lamps. These sources produce a broad spectral UV output with more intense mercury lines than the output at 254 nm which will cause artificially high readings from detectors with a broader response. This detector can be configured with optional attenuator filters at the time of purchase for measuring higher intensity germicidal UV sources.
