ILT400 - Belt Radiometer


ABLE offer the ILT400 Belt Radiometer, equipped with a solid-state detector for long term stability and reduced cost over traditional vacuum phototubes. The ILT400 all-in-one Belt Radiometer, comes in three versions: ILT400UVA measures UVA from 315 – 390 nm, ILT400BAV is designed for broadband covering 275 – 485 nm, and the ILT400UVV peaks in the visible spectrum covering 390 – 475 nm.

The ILT400 works with many lamp options from UV LEDs, Iron doped, H and D type lamps, as well as standard UV bulbs, but is not recommended for flashing or pulsed lamps.


  • Solid-state detector for lower noise and reduced cost.
  • Built-in rechargeable batteries with included charger means less downtime.
  • Graphically displays the performance of each lamp and reflector in your system. A stored reference plot allows you to compare, on-the-spot, the current performance of the system with the base line. The information is provided instantly. and allows the operator to see the uniformity of the illumination.
  • Measurement Range:
    • 5 mJ/cm2 to 20 J/cm2 (5 mW/cm2 to 20 W/cm2 (Graphic Profiling begins at 5 mW/cm2)
  • Temperature range: 10 to 60º C internal case temperature (greater ambient temperatures can be tolerated for short periods if the maximum internal case temperature of 60º C is not exceeded)
  • Belt speed: 1 to 80 feet-per-minute
  • Footprint:
    • 0.5 inches x 4.4 inches x 6.3 inches(12.7 mm x 111 mm x 161 mm)
  • Part Number/Spectral Response:
    • ILT400BAV (275 – 485 nm)
    • ILT400UVV (390 – 475 nm)
