UVC Photodetector TOCON_C5UVC
High-Sensitivity UVC Detector for Germicidal Lamp Monitoring, Sterilisation Process Validation, and Industrial UV-C Measurement Systems
The TOCON_C5UVC from SGLUX GmbH is a precision-engineered UVC photodetector designed for accurate measurement of germicidal ultraviolet radiation between 220 and 280 nm. Using a solar-blind silicon carbide (SiC) photodiode with an integrated low-noise transimpedance amplifier, the sensor delivers a linear 0–5 V DC output proportional to incident UVC irradiance.
Optimised for industrial and laboratory use, the TOCON_C5UVC provides superior spectral selectivity, fast response, and stable long-term performance under continuous UV exposure. Its rugged anodised aluminium housing and UV-grade quartz window ensure durability and reliability even in harsh environmental conditions.
Factory-calibrated and traceable to NIST/PTB standards, this sensor guarantees reproducible and standardised measurements. The TOCON_C5UVC is ideal for UVGI validation, surface disinfection systems, water sterilisation monitoring, and optical metrology applications requiring high precision and low noise.
Understanding UVC Photodetector TOCON_C5UVC
The TOCON_C5UVC utilises a solar-blind SiC photodiode that detects only UVC wavelengths (220–280 nm) while completely rejecting visible and infrared radiation. With its integrated transimpedance amplifier, it provides a direct 0–5 V DC signal for seamless use with SGLUX SENSOR MONITOR 5.0, VOLTCON, or SGCD4 systems.
It features a sub-second response time, minimal noise drift, and excellent linearity, ensuring accurate UVC measurement for sterilisation, calibration, and quality assurance.
The TOCON_C5UVC is factory-calibrated (NIST/PTB traceable) for dependable operation in industrial, laboratory, and environmental monitoring setups.
