Calibrated UV Sensor For Water Purifier – UV-ÖNORM
UV-ÖNORM – Calibrated UV-C Sensor for Water Purifiers and Certified UV Disinfection System Validation
The UV-ÖNORM from SGLUX GmbH is a high-precision, calibrated UV sensor developed for water purifiers and disinfection systems that must comply with international ÖNORM, DVGW, and US-EPA standards.
It measures germicidal UV-C irradiance (254 nm) emitted by mercury or UV-LED lamps, providing real-time monitoring of UV dose and lamp performance.
Built with a solar-blind Silicon Carbide (SiC) detector, it ensures high selectivity and accuracy under any lighting conditions.
The IP68-rated stainless-steel housing, combined with a UV-grade quartz window, allows direct installation into pressurised UV chambers for continuous operation.
Each sensor is factory-calibrated and traceable to NIST/PTB standards, ensuring long-term measurement reliability and regulatory compliance.
The UV-ÖNORM is ideal for drinking-water systems, industrial UV sterilisation, wastewater plants, and bottled-water processing units requiring certified UV dose validation.
Understanding UV-ÖNORM
The UV-ÖNORM sensor ensures water purifiers and UV disinfection systems operate within verified germicidal UV dose limits.
It directly measures UV intensity at 254 nm, enabling automated lamp-status monitoring, system validation, and safety control.
By using a solar-blind SiC photodiode sealed in a stainless-steel body, the sensor is immune to visible and IR light interference.
Its traceable calibration, temperature-compensated electronics, and waterproof IP68 design make it ideal for long-term submerged operation in water disinfection systems.
It ensures compliance with ÖNORM M 5873, DVGW W 294, and US-EPA UV guidelines for reliable UV dose monitoring.
