UV Index Photodetector (Erythema) – TOCON_E2
TOCON_E2 – UV Index Photodetector for Erythema-Weighted UV Measurement and Environmental Monitoring Applications
The TOCON_E2 from SGLUX GmbH is a high-precision erythema-weighted UV photodetector designed for accurate UV Index measurement and biologically effective radiation monitoring.
It combines a solar-blind SiC photodiode with a built-in transimpedance amplifier and a spectral correction filter matching the CIE erythemal (sunburn) action curve, producing a 0–5 V DC output proportional to UV intensity.
Optimised for the 280–400 nm wavelength range, the TOCON_E2 accurately quantifies UV radiation responsible for skin erythema and UV Index assessment in compliance with WMO and ISO standards.
Each sensor is factory-calibrated and traceable to NIST / PTB standards, ensuring high reproducibility, stability, and long-term accuracy.
Compact, rugged, and maintenance-free, the TOCON_E2 is ideal for meteorological stations, UV monitoring networks, medical safety systes, and environmental laboratories.
Understanding UV Index Photodetector (Erythema) - TOCON_E2
The TOCON_E2 is a UV Index photodetector that precisely measures erythemally effective ultraviolet radiation between 280 nm and 400 nm.
It integrates a solar-blind SiC detector and an optical correction filter reproducing the human skin’s erythema sensitivity, enabling reliable UV Index and biological exposure calculations.
The internal low-noise amplifier delivers a 0–5 V analog output, easily integrated into logging systems or SGLUX SENSOR MONITOR 5.0.
Its traceable factory calibration guarantees global comparability of UV Index data, making it indispensable for weather services, research laboratories, and occupational-safety monitoring.
