UVC Photodetector – TOCON_C1
TOCON_C1 – High-Sensitivity UVC Photodetector for Germicidal UV Measurement, Sterilisation Control, and Disinfection Systems
The TOCON_C1 from SGLUX GmbH is a precision-engineered UVC photodetector designed for accurate measurement of germicidal UV radiation (200–280 nm) used in sterilisation, disinfection, and photochemical applications. Built around a solar-blind silicon carbide (SiC) photodiode with an integrated low-noise transimpedance amplifier, it provides a linear 0–5 V DC output directly proportional to incident UVC irradiance. The detector’s spectral response peaks near 265 nm, perfectly aligning with the germicidal effectiveness curve for DNA and RNA inactivation. Factory-calibrated and traceable to NIST / PTB standards, the TOCON_C1 ensures accuracy, repeatability, and long-term stability in both industrial and laboratory use. Compact, rugged, and interference-free, it is ideal for UVC source characterisation, sterilisation chamber monitoring, water and air purification systems, and UV-C LED testing, ensuring reliable, real-time control of disinfection performance.
Understanding UVC Photodetector - TOCON_C1
The TOCON_C1 is a solar-blind UVC photodetector that provides accurate measurement of germicidal radiation between 200 and 280 nm, with peak sensitivity at 265 nm. Its built-in amplifier outputs a linear 0–5 V signal, enabling direct connection to controllers, data loggers, or SGLUX SENSOR MONITOR 5.0 systems. The SiC detector’s intrinsic UV selectivity ensures complete insensitivity to visible and infrared light, making it ideal for controlled UV-C measurement in harsh industrial conditions. With factory calibration traceable to NIST/PTB, the TOCON_C1 guarantees precise, stable, and repeatable readings for UVC source verification, disinfection control, and UV safety compliance.
