Narrowband Germicidal Detector

Configured specifically to measure germicidal effectiveness at 254 nm.

Measurement Range: 2e-6 to 2e-2 Watts/cm
Hazard Spectral Range: 249 - 259 nm, Center wavelength at 254 nm.
Dimensions: 66 mm x 42 mm diameter
Order part number: ILT2400 (meter), SED240/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. Please consult one of our knowledgeable sales representatives for more information.
