It can be accurately measured from low luminance to high luminance, and the high luminance can reach 100000cd/m²

Ultra-high Speed

0.16 times per second @0.0003cd/m²，once per second @0.01cd/m²

Extreme Precision
The luminance accuracy up to 2%@0.01cdm²
The chrominance accuracy up to 0.003@0.01cdm²

Real-time Display
Display the test data in all directions with OLED screen

Easy to Integrate
Universal SDK/protocol for easy system integration and automatic measurement

CM-20 Colorimeter Advantage

For Gamma test, highly sensitive sensors and computing power enable color adjustment of products on the production line, effectively increasing productivity.
It is possible to perform automatic single measurement and continuous multiple measurements.
Wide luminance measurement range: 0.0003~100000cd/m², fast measurement of full range luminance through automatic gain control algorithm.
Flicker measurement, support VESA, JEITA, FMA and other modes.
Based on CIE1931 criteria, almost perfect visual function matching.
The OLED screen displays the measurement data in real time, and the measurement data can be transmitted through USB/RS232 connection to a computer.
