The UVB313E UV radiation meter is specialized in detecting the intensity of UVB ultraviolet radiation emitted by the sun or lamps. The measurable wavelength range is 290nm-325nm, with a center wavelength of 315nm.
This detector utilizes a low-power digital chip and features stable performance with strong applicability after strict spectral and angular characteristics correction. The split-type design makes it easy to carry, while the built-in button battery provides strong endurance. The external probe features two telescopic handles for freely adjustable length and convenient measurement.
