The radiometers measure UV light intensity for a specific wavelength (254nm, 312nm or 365nm). They are designed for an accurate and direct measurement of the UV radiation. All our radiometers use a silicon photo-electric for a direct measurement of the UV intensity and thus do not convert UV into visible light.
VLX-3W
The VLX-3W is a highly accurate and user friendly radiometer. The radiometer is controlled by a microprocessor to measure the UV radiation dosage according to two parameters: time (mn or sec) or energy (J:cm²). The VLX-3W is connectable to three interchangeable sensors.
UV-3W
UV-3W are single wavelength radiometer. They measure the UV intensity for either short wave (254nm), middle wave (312nm) or long wave (365nm).
