"The Eppley Total Ultraviolet Radiometer (TUVR) measures total short-wave solar radiation (295 to 385 nm) with sensitivity of approx. 150 microV/Wm-2. The unit is of brass construction and includes adjustable leveling screws and a circular spirit level. The instrument utilizes a hermetically sealed selenium barrier-layer cell which is protected by a quartz window. An encapsulated narrow bandpass (interference) filter limits the spectral response of the photocell."@en . .
