Simplifying UV-C Light Measurement

UV Elevator Disinfection

The ILT770-UV light intensity meter and measurement system as everything you need to start validating the light output of your UVC LED’s and other narrow-band UVC light sources. The  ILT770-UV is specifically configured and calibrated to 270 nm where most pathogens, including the COVID-19 virus, are deactivated (See graph above).  With the touch of a button the ILT770 will do the following:

  • Confirm the amount of light reaching a surface 
  • Calculate the dose in J/cm2 
  • Graph the output over time 
  • Validate the Min max and average irradiance (mW/cm2)  
  • Save the results for exporting to your PC 

Validating your UVC disinfection system does not need to be a complex task.  The ILT770 simplifies light measurement by automatically selecting the input range (auto-ranging) so the user does not need to manually dial it in.  Easily toggle between irradiance and dose readings with a single button. The graphical interface not only displays the uniformity of the light over time, but also calculates the min, max and average.  The detector is attached with 3' cable, reducing the risk of user exposure. The Sensors low profile housing makes lamp access easy.


Disinfection Applications

The ILT770-UV is perfect for validation UV disinfection systems for:

  • Elevators cabs
  • Escalator and moving walkway handrails
  • UV disinfection chambers
  • Air purification systems
  • Water purification systems
  • Remote deployed room disinfection systems
  • Hand-held germicidal lamp disinfection systems

About ILT

ILT is an USA-based company.  We have been designing light measurement systems since 1965.  All of our meters are built and calibrated on-site at our Peabody, Massachusetts head quarters.  We are an ISO9001 certified facility and our calibration lab is ISO17025 accredited.  All of our meters come with an ISO17025 accredited calibration certificate and are NIST traceable.  

About Ultraviolet Germicidal Irradiation

Also referred to as UVGI, it is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.  The ILT770-UV will allow users to verify the output of their lamps is effectively irradiating the exposed areas.
