LI-210R Visible Light Illumination SensorMeasure the brightness of light visible to the human eye. LI-210R is suitable for evaluating the brightness of work areas, display lighting, indoor lighting, etc. The measurement unit is lux or klux, and the measurement wavelength is 450-650nm.

working principle
The LI-210R uses a silicon photodiode with a precise filter to measure illumination and is sensitive to the visible light spectrum range. The sensor head is exquisitely designed to quickly guide rainwater and obtain precise cosine response.

Application field

√ Indoor lighting measurement
√ Measurement of uniform light intensity
√ Glass transparency effect, etc

Main advantages

The spectral response curve closely matches the CIE standard observation curve
Ensure uniform sensitivity within the range of 82 ° incident angle
√ Detachable sensor head, easy to install and disassemble, convenient for maintenance and calibration
