Radiometric UV Sensor – UV Air
UV Air – Radiometric UV-C Sensor for Air Disinfection, Sterilisation and Environmental UV Monitoring Applications
The UV Air from SGLUX GmbH is a precision-calibrated radiometric UV-C sensor designed for air disinfection and UV sterilisation systems.
It measures germicidal ultraviolet irradiance in the 230–280 nm range, allowing real-time monitoring of UV dose in air-handling units, HVAC systems, and UV-C sterilisation chambers.
Using a solar-blind Silicon Carbide (SiC) photodiode and NIST/PTB-traceable calibration, the UV Air ensures accurate, repeatable irradiance readings unaffected by visible or IR light.
Encased in a rugged IP65 aluminium housing with a UV-grade quartz window, the sensor is built for long-term stability and easy integration into industrial, laboratory, and environmental systems.
The UV Air guarantees reliable, maintenance-free UV monitoring for ensuring safe, efficient, and validated air sterilisation performance across critical sectors such as healthcare, HVAC, and cleanroom applications.
Understanding Radiometric UV Sensor - UV Air
The UV Air sensor measures germicidal UV intensity (254 nm) used in air sterilisation systems to inactivate airborne pathogens.
Its SiC solar-blind photodiode outputs a linear voltage proportional to UV irradiance, ensuring precise feedback control for UV-C lamp or LED performance.
The IP65-rated aluminium housing protects it from dust and humidity, making it suitable for long-term installation in HVAC ducts or sterilisation chambers.
Factory-calibrated to NIST/PTB standards, the UV Air provides traceable UV dose data, ensuring regulatory compliance and energy-efficient disinfection for healthcare, transport, and industrial environments.
