High Accuracy UV Index Sensor UV-Surface_UVI
High Accuracy UV Index Sensor UV-Surface_UVI for Professional Solar Radiation and Erythema-Weighted Environmental Monitoring
The UV-Surface_UVI from SGLUX GmbH is a high-precision erythema-weighted UV Index sensor designed for accurate, continuous measurement of solar ultraviolet radiation.
Using a Silicon Carbide (SiC) photodiode, integrated optical erythema filter, and precision amplifier electronics, it provides a 0–5 V linear output directly proportional to the UV Index (UVI).
Its spectral response follows the CIE erythema action curve, ensuring true correlation with internationally recognised UVI standards.
Built in a rugged, UV-resistant aluminium housing with temperature-compensated electronics and IP67 protection, the sensor is ideal for permanent outdoor installation in meteorological stations, smart-city monitoring networks, and public health alert systems.
Each unit is factory-calibrated and NIST/PTB-traceable, guaranteeing reproducible, globally comparable measurements.
The UV-Surface_UVI delivers research-grade precision and durability for real-time UV Index monitoring across industrial, environmental, and scientific applications.
Understanding High Accuracy UV Index Sensor UV-Surface_UVI
The UV-Surface_UVI converts erythemally effective UV irradiance (280–400 nm) into a linear voltage output that directly represents the UV Index.
Its SiC detector provides exceptional solar blindness (> 10¹⁰ visible suppression) and long-term stability under extreme outdoor conditions.
Active temperature compensation maintains accuracy throughout seasonal variations, while its weather-sealed construction prevents signal drift due to humidity or aging.
Calibrated against NIST/PTB standards, the sensor supports scientific UV monitoring, environmental safety assessments, and smart-infrastructure data systems.
It delivers dependable, real-time UV Index information for professional and public health applications.
