LU100 luminance detector is a precision instrument for professionally detecting the brightness of light outside the tunnel. The optical imaging structure is adopted to simulate the spectral response and receiving characteristics of the human eye, and even to detect the average brightness within the field of view.

Performance Features:

Ø  According to the human visual spectrum curve specified by C.I.E, it is calibrated with a special high-efficiency filter to meet the visual characteristics

Ø  Professional optical lens imaging measurement;

Ø  Continuous linear proportional output, accurate and sensitive measurement range of corresponding equipment;

Ø  Multiple signal output methods to adapt to different usage methods;

Ø  Local data storage to avoid data loss under abnormal conditions;
