CM-200 Color Luminance Meter

CM-200 Color Luminance Meter has a portable exterior design, built-in lithium battery and power adapter, and can be used to measure various luminance conditions and non-contact luminance and chrominance measurement.

CM-200 Color Luminance Meter Characteristic

  • With wide luminance measuring range and optional illumination probe.
  • Circuit design with low noise and high sensitivity. 
  • Equipped with XYZ filters close to the visual function of the human eye. 
  • Various measurement modes are available to automatically select the most suitable measurement time. 
  • The data is visually displayed on the external display. 
  • Luminance is as low as 0.01cd/m^2.
  • Target color can be set for chromatic aberration measurement.
  • Up to 20 user calibration channels. 
  • Quickly obtain the luminance of objects in the measured area without touching the sample and without being affected by the surrounding area.
  • Through the standard software, the instrument can be controlled for continuous reading interval measurement, custom measurement, and the software outputs the measurement data.
