LI-COR LI-210R Photometric Sensor

Photometric Sensor

LI-210R

The LI-210R Photometric Sensor measures light with the same sensitivity as a typical human eye. The photometric sensor is ideal for evaluating illumination in work areas, exhibits, interior lighting, and in public spaces. Measurement units are lux or klux.

Why choose the LI-210R Photometric Sensor?

Spectral response closely matches the CIE Standard observer Curve
Excellent cosine response—sensitive to light from all directions up to an 82° angle of incidence
Detachable sensor simplifies installation and removal, making it ideal for platforms with complex cabling

How does it work?

The LI-210R measures light with a precision filtered silicon photodiode that is sensitive to light in the visible spectrum.
