AccuMAX XR-1000 Unit + XS-555/L Luminance Sensor

AccuMAX XR-1000 Readout Unit + XS-555/L Luminance Sensor

The XS-555/L luminance sensor is ideal for technicians performing radiographic examinations


Luminance is typically used to measure uniformly radiating surfaces, such as backlit panels, film viewers and monitors. The AccuMAX XS-555/L luminance sensor detector measures the brightness of a visible light source and unlike many competitive units, allows the user the choice of displaying the results in three distinct units of measure:

  • Candelas per square meter (cd/m2)
  • Candelas per square foot (cd/ft2)
  • Footlamberts (fL)


  • Meets ASTM and MIL standards.
  • Extremely versatile. Provides luminance measurements in cd/m2, cd/ft2 and fL.
  • Ideal for radiographic examinations requiring film viewer output measurements.
  • Connects easily to the digital readout unit via a USB cable.
