altPhoseon Technology (Hillsboro, OR) introduces a family of ultraviolet (UV) LED radiometer products that provide customers a simple, reliable way to measure and maintain their UV LED light sources. The radiometers are optimized for 380-420 nm wavelengths and provide traceable calibration to ensure accurate measurements. A fixed-location model measures peak irradiance, and an in-motion model measures dose as well as peak irradiance. An optional SD card allows irradiance and temperature profile mapping on PC displays.
