UVC Germicidal Radiometer : UVKey | EIT 2.0

UVKey™ is a germicidal radiometer with a 254 nm response and dynamic range optimized for UVC treatment of hospital rooms and other room disinfection applications


UVKey is optimized for the control of germicidal UVC lamps at 254 nm treatment of hospital rooms for instance.

With a quick and easy setup, he is perfect for accurately measuring the UVC level in order to sterilize an environment by displaying the numerical value of the UVC does.

Features :

  • Delivers precise NIST traceable numerical readout of the dose (mJ/cm2)
  • Eliminates the need for user interpretation of color and minimizes batch-to-batch discrepancies linked to radiochromic films
  • Simple one-button operation ensures user-friendliness, while the IP67 sealed UVKey™ design safeguards against dust and liquid splashes.
  • Make an unlimited number of measurements during its 6-month life span
