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-200R?
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.
