Response Curve

High-Intensity Germicidal / UV Measurement System for measurement of Low pressure mercury lamps. Can be combined with our NS254 narrow band filter to measure the 254 nm output of all types of UV sources including Xenon, Mercury, LED and more.

  • Measurement Range SED270/QT: 1e-9 to 1 W/cm2
  • Measurement Range SED270/NS254/QT: 4e-9 to 3 W/cm2
  • Spectral Range: 215 – 350 nm (249-259 nm with NS254 filter)
  • Dimensions: 60 mm x 42 mm diameter. (65 x 42 mm with Filter)
  • Order part number: ILT5000 and SED270/QT or  SED270/NS254/QT 


ILT SED270 Detector








Note:  the QT is also available with 1, 3, 5 and 7 mm apertures for testing LED’s, small focused beams and for testing uniformity of the UV over the irradiated area. The apertures will also decrease the sensitivity allowing measurements at higher light levels.


Filters and input optics are removable and may be ordered separately from the detector assembly to allow filter and input optic swapping



Note: For simultaneous multi-sensor data logging, ILT also offers the ILT6000 Rack-Mount Radiometer System with the same specifications as the ILT5000 in a 2-10 unit, rack mountable housing.
