LM-200 Photometer

LM-200 Photometer has a portable exterior design, built-in lithium battery and power adapter, and can be used to measure various brightness conditions and non-contact luminance measurement.

LM-200 Photometer Characteristic

  • With wide luminance measuring range and optional illumination probe.
  • Circuit design with low noise and high sensitivity.
  • Equipped with Y 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. 
  • Measurements of luminance, luminance difference, ratio, peak and valley.
  • 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.

LM-200 Photometer Application

  • Luminance measurement of small light sources
  • Luminance measurement of various signal lights
  • Luminance measurement of non-contact surface
  • Luminance measurement of LCD display monitor
  • Luminance measurement of black and white display
  • Luminance measurement of projector
  • LED large screen measurement
