LM-200 Luminance Meter

LM-200 Luminance Meter Characteristic

LM-200 Luminance Meter has a portable exterior design, built-in lithium battery and power adapter, and can be used to measure various luminance conditions and non-contact luminance measurement.
With wide luminance measurement 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 0.001cd/m2.
Measurements of luminance, luminance difference, ratio, peak and valley.
Up to 20 user calibration channels.
Quickly obtain the chrominance 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 interval measurement and custom measurement, and the software outputs the measurement data.
