The UVA-UVV Series UV Radiation Meters are precision instruments designed for detecting ultraviolet radiation intensity from various sources including sunlight and artificial lamps.
UVA365: Specialized for UVA ultraviolet radiation detection with measurable wavelength range of 320nm-390nm and center wavelength of 365nm.
UVV405: Designed for UVV ultraviolet radiation detection with measurable wavelength range of 360nm-460nm and center wavelength of 405nm.
UVV420: Engineered for UVV ultraviolet radiation detection with measurable wavelength range of 370nm-470nm and center wavelength of 420nm.
These instruments feature low-power digital chips, stable performance after strict spectral and angular characteristics correction, split-body design for portability, built-in button batteries with strong endurance, and external probes with telescopic handles for adjustable measurement length.
