Radiometric Sensors

  • Product No:221 / 222 / 247 / 260
  • Manufacturer:Gamma Scientific

UDT Instruments, a Gamma Scientific company, produces precision radiometric sensors for a wide range of radiometric testing applications.

UDTi radiometric sensors are ideally suited for OEMs, value-added resellers and any company that is interested in accurately measuring light intensity and brightness.

When coupled with an optometer, these sensors are used to measure radiant flux, irradiance, radiant intensity and radiance.
