AccuMAX + XS-555/L Luminance Sensor

The perfect accessory for the AccuMAX XRP-3000 Digital Radiometer/Photometer Kit. Ideal for technicians performing radiographic examinations.

Luminance is typically used to measure uniformly radiating surfaces, such as x-ray film viewers, backlit panels, and computer monitors and flat screen displays. The AccuMAX XS-555/L luminance sensor detector measures the brightness of a visible light source. A unique feature is that the AccuMAX 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.
