The UV spectral range is subdivided into two bands: UV-A and UV-B. In contrast to the traditional technology used in UV-radiometers, the MS-10S (315-400 nm) and MS-11S (280-315 nm) have an outstanding stability and measurement repeatability in harsh UV applications. The two UV-radiometer series with Smart technology provide multiple outputs and embedded sensors for remote performance diagnostics. Body-temperature, relative- humidity and tilt-angle can be permanently monitored through the digital interface (Modbus 485 or SDI-12).

Similar to all EKO pyranometers, the UV-radiometer models are based on the compact and light-weight universal EKO sensor platform which offers several benefits. All sensors can be easily combined with the MV-01 ventilation/heater for accurate UV measurement in harsh outdoor environments.
