UV Sensor For Surface Disinfection – UV-DVGW
UV-DVGW – Precision UV-C Sensor for Surface Disinfection, Sterilisation and Process Validation in Industrial Applications
The UV-DVGW from SGLUX GmbH is a precision UV-C irradiance sensor specifically designed for surface disinfection, sterilisation, and validation processes in industrial and laboratory environments.
It measures germicidal ultraviolet radiation at 254 nm, verifying lamp performance and ensuring regulatory compliance according to DVGW, ÖNORM, and US-EPA standards.
Built with a solar-blind Silicon Carbide (SiC) photodiode, the UV-DVGW delivers highly selective UV-C response, unaffected by visible or IR light.
Encased in a stainless-steel housing with a quartz optical window, the sensor ensures long-term stability under continuous high-intensity UV exposure.
Factory-calibrated to NIST / PTB standards, it provides traceable accuracy for real-time irradiance measurement in surface sterilisation chambers, conveyor systems, medical equipment disinfection units, and packaging lines.
The UV-DVGW is compact, durable, and maintenance-free, making it ideal for validation and quality assurance of UV disinfection systems.
Understanding UV-DVGW
The UV-DVGW sensor quantifies germicidal UV intensity emitted by disinfection lamps or LEDs at 254 nm, ensuring surfaces receive adequate UV dose for microbial inactivation.
Its solar-blind SiC detector generates a voltage proportional to incident UV energy, enabling accurate measurement of sterilisation efficiency.
With its rugged stainless-steel body and temperature-compensated electronics, the sensor performs reliably in industrial and medical disinfection setups.
It forms an essential component in lamp validation, process verification, and hygiene compliance, guaranteeing effective UV exposure for surface sterilisation systems in food, pharma, and healthcare applications.
