Universal UV Radiometer – SXL 55
Universal UV Radiometer SXL 55 for Precision Measurement of UV Irradiance Across UVA, UVB, and UVC
The Universal UV Radiometer – SXL 55 is a high-precision, multi-range ultraviolet measuring instrument developed for accurate quantification of UV irradiance and dose across UVA, UVB, and UVC spectral regions. Designed for laboratory, industrial, and environmental applications, it features interchangeable, factory-calibrated detectors traceable to NIST/PTB standards, ensuring consistent, repeatable results. The SXL 55 supports measurement ranges from µW/cm² to W/cm², allowing use in both low-level and high-intensity UV systems. Its digital control unit provides real-time readout, data logging, and automatic detector recognition, ensuring user-friendly operation. Robust and portable, it serves as a universal reference for UV curing, disinfection, phototherapy, and photochemical research. The SXL 55 combines reliability, traceable calibration, and spectral flexibility to deliver professional-grade UV measurement performance for research, QA, and process validation.
Understanding Universal UV Radiometer - SXL 55
The SXL 55 Universal UV Radiometer functions as a modular, high-accuracy UV measurement platform. It operates with plug-in detector heads tailored for UVA (315–400 nm), UVB (280–315 nm), or UVC (200–280 nm), automatically identifying calibration data upon connection. The system displays instantaneous irradiance (mW/cm²) and integrates total dose (mJ/cm²) for process validation. With a digital control interface, temperature-compensated amplifiers, and traceable calibration, it ensures dependable UV quantification in research and production environments. Its versatility and precision make it a preferred tool for sensor calibration laboratories, UV curing system validation, and medical device testing.
