Digital UV Transmission Meter Spectrum 400Z
An ultraviolet radiation light meter which measures the average percentage of ultraviolet rays transmitted through an optical lens. The Digital Ultraviolet Transmission Meter is designed to verify the ultraviolet protection level accurately and consistently. It’s capability extends over the ultraviolet spectrum from 320 to 400 nanometers. UV sensor opening is located on top of meter for easier measuring of UV protection in the lenses that are still in their frames.
