MLM 1009

This is the professional portable instrument that allows to characterize light fixtures/light sources in terms of illuminance, chromaticity coordinates and color temperature.

  • L class sensor for illuminance of LED and traditional sources (0 ÷ 300.000,00 Lux)
  • Measurement range for RGB components 0-256 (whole numbers)
  • Measurement range for chromaticity coordinates x, y and z 0-0.55 (as per CIE diagram)
  • Measurement range for color temperature 0 – 15.000° Kelvin
  • Excellent quality-price ratio
  • Free post-selling assistance and support

MLM 1009 is a multi-photometer equipped with a state-of-the-art portable calculation hardware unit able to process measurement data with high resolution and accuracy levels.


MLM 1009 is equipped with a photometric sensor with three programmable light-frequency RGB 8red, green and blue) converters and with a 1 meter connection cable.

The assembly of a high sensitivity and configurable Si photodiode and of a current-frequency converter into a single CMOS integrated circuit enables high performance measurements.


The collected data are processed by a state-of-the-art processing unit equipped with a user-friendly interface with a button for each measurement function and a display to show measurement results.


  • LED sources illuminance
  • Traditional (non-LED) light source illuminance
  • absolute values of RGB light components
  • chromaticity coordinates x,  y (CIE 1931 color space)
