Universal UV Radiometer – SXS
Universal UV Radiometer SXS for Accurate Measurement of UV Irradiance and Dose in All Spectral Ranges
The Universal UV Radiometer – SXS is a compact, precision-grade ultraviolet measuring instrument engineered for accurate detection of UV irradiance and total dose across UVA, UVB, and UVC spectral regions. It is designed for laboratory and industrial use where reliability, portability, and precision are essential. The SXS operates with pre-calibrated, interchangeable detector heads traceable to NIST/PTB standards, enabling high-accuracy measurements in multiple UV applications. Featuring an intuitive digital display, temperature-compensated electronics, and fast response time, the SXS delivers real-time monitoring of UV sources ranging from low-intensity laboratory emitters to high-power industrial lamps. Its robust housing and user-friendly operation make it ideal for UV curing, disinfection validation, phototherapy calibration, and material ageing analysis. The SXS combines German engineering precision with simplicity, ensuring traceable, repeatable, and field-ready UV measurement performance for professionals in research, production, and regulatory environments.
Understanding Universal UV Radiometer - SXS
The SXS Universal UV Radiometer provides direct measurement of UV irradiance (mW/cm²) and total dose (mJ/cm²) using high-accuracy photodiode detectors tailored for each UV spectral range. When connected, each detector automatically loads its calibration data, allowing instant plug-and-measure functionality. The SXS is lightweight and portable, making it suitable for both laboratory calibration and on-site verification of UV systems. Its fast response, broad dynamic range, and traceable accuracy make it indispensable in industrial curing, disinfection monitoring, and R&D applications where consistent UV exposure validation is critical.
