Radiometric UV Sensor – UV Surface
UV Surface – High-Precision Radiometric UV-C Sensor for Surface Disinfection, Sterilisation and Process Validation Applications
The UV Surface from SGLUX GmbH is a high-accuracy radiometric UV-C sensor engineered for surface disinfection and sterilisation verification.
It measures germicidal ultraviolet irradiance at 254 nm, enabling precise validation of UV-lamp or UV-LED performance in medical, pharmaceutical, and industrial cleaning applications.
Equipped with a solar-blind Silicon Carbide (SiC) photodiode, the UV Surface provides reliable measurements free from visible or IR interference.
Its flat optical geometry ensures direct exposure measurement on planar surfaces, while the stainless-steel, IP65-rated housing offers long-term durability under intense UV flux.
Factory-calibrated and traceable to NIST/PTB standards, the sensor delivers linear analog output (0–5 V) for integration with process controllers and data loggers.
The UV Surface is ideal for UV-C dose verification in medical equipment, packaging, conveyor lines, and surface-sterilisation research, guaranteeing validated, traceable, and repeatable results.
Understanding Radiometric UV Sensor - UV Surface
The UV Surface measures germicidal UV intensity directly at the target surface, ensuring that sterilisation processes deliver the required disinfecting dose.
It uses a solar-blind SiC detector with flat-top optical geometry optimised for accurate surface irradiance mapping.
The IP65 stainless-steel enclosure protects it from dust, moisture, and UV degradation, while the factory calibration provides traceable accuracy for regulated industries.
With fast response, wide dynamic range, and cosine-corrected accuracy, the UV Surface serves as a reliable instrument for UV-C process validation, lamp testing, and sterilisation quality assurance across laboratory and industrial environments.
