Description: Exchangeable sensors, big LCD display with 4 lines
Measurement range: Intensity 0 to 250 mW/cm², energy 0 to 9999 J/cm², time 0 to 99 hours


The radiometers from Vilber Lourmat measure UV light intensity for a specific wavelength (254 nm, 312 nm or 365 nm). They are designed for an accurate and direct measurement of the UV radiation.

  • Energy<: 0 to 99999 J/cm²
  • Time: 0 sec to 99 hours
  • Choice between four different, interchangeable sensors
  • Stop button and storage of minimum and maximum intensity

For all models, the measurement of the UV radiation is done by a silicon photo-electric for the direct measurement of the UV intensity. There is no UV light converted into visible light which may cause incorrect calculations. The VLX-3W is a highly accurate and user friendly radiometer. It is controlled by a microprocessor to program and to measure the UV radiation dosage according to two parameters: time (min or sec) or energy (J/cm²). The VLX-3W is connectable to three interchangeable sensors, which have to be used one at a time. The sensors have to be ordered separately, they are available in 254 nm, 312 nm or 365 nm.
