Short Description

The Lutron UV-340A is a professional digital UV light meter designed for accurate measurement of UVA and UVB ultraviolet radiation. Equipped with a precision UV sensor featuring a cosine correction filter, the instrument measures UV irradiance over the 290 to 390 nm spectral range with high accuracy. Its separate probe design, dual measurement ranges, and microprocessor-based circuitry make it ideal for UV sterilization monitoring, laboratory research, photochemical processes, welding safety, printing, and industrial quality control.
