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.
