LI-COR LI-210R [LI-210R-BNC-50] Photometric Sensor w/ Microamp Output, 50m Cable and BNC Connector

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.

The LI-210R measures light with a precision filtered silicon photodiode that is sensitive to light centered in the visible spectrum. It responds to light with sensitivity that is close to the human eye, as described by the International Commission on Illumination (CIE) Standard Observer Curve. Cosine corrected to 82° incident angles for accurate measurements when the light source is not directly overhead.
