EIT UVKey – Germicidal UVC Radiometer

UVKey™ is a germicidal UV measurement device from EIT, designed with a spectral response at 254 nm and a dynamic range optimized for UVC processing.
The device provides precise digital readings of UV exposure (measured in mJ/cm²), traceable to NIST standards to ensure measurement reliability.

UVKey™ eliminates reliance on user color perception and removes batch-to-batch variability associated with radiochromic films, improving both accuracy and consistency.

With a compact, single-button design, UVKey™ is easy to operate. The device is also IP67-rated, sealed against dust and water spray, making it ideal for use in specialized disinfection environments.
