Brochure

All Vilber's radiometers use a silicon photo-electric sensor for a direct measurement of the UV intesity and thus do not convert UV into visible light.

Description

Vilber radiometers record the intensity of ultraviolet radiation for a specific UV wavelength (long wave, short wave, medium wave).

The intensity of UV radiation refers to the UV intensity and is measured in mW/cm2. The VLX-3W radiometer indicates the amount of UV energy on a surface for a specific time. The data is defined in mJ/cm2 (milli-Joule per square centimeter). Small and convenient, the VLX-3W radiometer is of modular construction with a choice of three sensors to record UV radiation in the spectral range from 254nm to 365nm. With a wide measuring range from 0.1 to 250 mW/cm2, our radiometers instantly indicate readings on a large LCD display.

Depending on the spectral range to be measured, a suitable sensor is attached to the VLX-3W base unit:

  • Silicon photocell for direct measurement of UV radiation. No conversion to visible light is required.
  • Interference filter to select the appropriate UV band and eliminate other unwanted radiation.
  • Not sensitive to infrared.
  • No electronic components in the sensor to avoid any temperature disparity.
  • Protection by quartz disc on cellular filter
  • Carbon shielded cable (1 meter)
  • Microprocessor controlled
  • Designed to operate at 254 nm, 312 nm or 365 nm
  • Independent sensor (purchased separately) for each wavelength
