Simplifying Phototherapy Light Measurements

The ILT770-NVUVB311 intensity meter and measurement system as everything you need to start validating the light output from your phototherapy lamps. It's not enough to trust the manufacturer's specifications. You must verify that the system you're entrusting the health and well being of your patients to is doing what it says - and applying the correct UV exposure levels during treatment.

The ILT770-NBUVB311 is specifically configured and calibrated to 311 nm.  The meter's narrow band filter is specifically designed to measure UVB systems, such as Philips TL-10 lamps and UVB LED’s. Regardless of the light source your system uses, with the touch of a button the ILT770 will do the following:

  • Confirm the amount of light reaching a patients skin
  • 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 phototherpay light source 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.

ILT is a USA-based company that has been designing light measurement systems since 1965.  All of our meters are built and calibrated on-site at our Peabody, Massachusetts headquarters.  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.
