Photo-Electric Sensor
Direct measurement of the UV intensity.
Time Or Energy Measure
The intensity is measured in mW/cm² and the energy in joules/cm².
Microprocessor Controled
Smart and easy to use.
Interchangeable Sensor
Wavelength dependent sensors could be used one at a time.
All our radiometers use a silicon photo-electric sensor for a direct measurement of the UV intesity and thus do not convert UV into visible light.
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
