UV Index Photodetector (Erythema) – TOCON_E_OEM
TOCON_E_OEM – Precision UV Index and Erythema Photodetector for Accurate Solar UV Monitoring and Dosimetry
The TOCON_E_OEM from SGLUX GmbH is a compact, factory-calibrated UV Index photodetector specifically designed for accurate erythema-weighted UV measurement in solar monitoring, environmental research, and safety applications. It integrates a UV-sensitive photodiode with an internal low-noise transimpedance amplifier to deliver a linear 0–5 V DC output proportional to incident erythemally weighted irradiance. Its spectral response precisely matches the CIE erythema action curve (ISO 17166 / CIE S007-1998), enabling direct correlation with human skin UV exposure and global UV Index standards. The TOCON_E_OEM offers traceable NIST/PTB calibration, long-term stability, and excellent cosine response for outdoor and laboratory measurements. Built within a rugged anodised aluminium TOCON housing, it’s ideal for UV Index monitoring stations, solar simulators, environmental chambers, and OEM sensor integrations requiring accurate, maintenance-free, and reliable erythemal UV evaluation.
Understanding UV Index Photodetector (Erythema) - TOCON_E_OEM
The TOCON_E_OEM is an erythema-weighted UV detector optimised for precise UV Index measurement. Its internal amplifier provides a stable 0–5 V analog signal, directly readable by data loggers, PLCs, and SGLUX SENSOR MONITOR 5.0 systems. With spectral matching to the CIE erythema response, it ensures reliable simulation of biological skin response to UV exposure. The detector’s factory calibration (traceable to NIST/PTB) guarantees accurate, repeatable readings across various lighting and environmental conditions. Compact, linear, and temperature-stable, the TOCON_E_OEM is the professional choice for solar UV measurement, environmental monitoring networks, and safety compliance instrumentation.
