UV Spectro – Precision UV Spectral Radiometer

Accurate measurement, versatile application

The UV Spectro is a high-precision UV spectral radiometer that combines the functionality of a spectrometer and a UV integrator in a single compact device. Covering the UV range from 200 to 440 nm, it measures both spectral composition and intensity profiles, making it ideal for medium-pressure UV lamps or UV LED applications.

Its ultra-flat design with a height of only 14 mm allows seamless pass-through measurements. During operation, the device continuously records individual wavelengths using a specially designed diode array, storing all results in its internal memory. Measurements of intensity and dose can be displayed numerically or graphically on the built-in display, with bar graphs illustrating irradiation profiles and accumulated dose.

The UV Spectro operates fully autonomously and allows easy data transfer to a PC via USB. Up to 50 measurement series can be stored internally, enabling comparison over time and reliable documentation of UV processes for quality control and process optimization.
