UVC Photodetector – TOCON_C4UVC
TOCON_C4UVC – Precision UVC Photodetector for Germicidal Lamp Monitoring and Disinfection Efficiency Measurement Applications
The TOCON_C4UVC from SGLUX GmbH is a precision-calibrated UVC photodetector designed for accurate germicidal UV-C radiation measurement in disinfection, sterilisation, and industrial monitoring applications.
It integrates a solar-blind Silicon Carbide (SiC) photodiode with a built-in low-noise transimpedance amplifier, providing a 0–5 V DC output directly proportional to incident UVC irradiance.
The sensor’s spectral sensitivity peaks near 254 nm, perfectly matching the emission of low-pressure mercury germicidal lamps and UVC LEDs.
Each unit is factory-calibrated and traceable to NIST / PTB standards, ensuring high accuracy, repeatability, and long-term stability.
Compact, rugged, and resistant to solar and visible light interference, the TOCON_C4UVC is ideal for UVC intensity monitoring, system calibration, sterilisation validation, and environmental safety control in industrial, medical, and research environments.
Understanding UVC Photodetector - TOCON_C4UVC
The TOCON_C4UVC is a solar-blind UVC photodetector engineered for precision measurement of germicidal ultraviolet radiation.
It features a SiC photodiode that is inherently insensitive to visible and infrared light, ensuring exclusive detection of wavelengths between 210 nm and 280 nm.
The internal low-noise amplifier provides a stable 0–5 V analog output, allowing direct connection to meters, data loggers, or SGLUX SENSOR MONITOR 5.0.
Calibrated to NIST/PTB standards, it delivers reproducible, traceable results ideal for UVC disinfection validation, lamp calibration, and air/water sterilisation system monitoring where accuracy and spectral purity are essential.
