Chroma 71241 high accuracy universal measuring probe adopts the design of non-contact type measurements to measure the luminance and chromaticity of display panels.

Developed with the most advanced digital signal processor and the technology of optoelectronic transfer as well as precision optical parts and circuit design, the 71241 high accuracy universal measuring probe is capable of performing high speed, accurate and stable color tests.

71241 complies with the color matching function sensor of CIE 1931 that can measure the luminance and chromaticity of display panel accurately.

Users can switch to various types of chromaticity coordinates freely including four display types of chromaticity coordinates xyY, TΔuvY, u’v’Y, XYZ, and FMA, FLVL two flicker measurements modes.

The 71241 that is designed to test the LCD characteristics with LED backlight is able to meet the low luminance test requirements of 0.001cd/m²

The 71241 also has the functions of contrast measurement, result judgment and programmable test items that can fulfill the auto test requirements to enhance the production efficiency.

The optical measurement software incorporated by Chroma 71241 is able to do chromaticity, luminance, Flicker and Gamma measurements on PC, and then show the measured data on CIE 1931 and CIE1976 UCS chromaticity coordinate chart directly.

Chroma 71241 high accuracy universal measuring probe has 100 channels of built-in memory for storing the value of standard colors and calibrated data.
