LI-210R Photometric Sensor
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
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
Absolute Calibration: ± 5% traceable to the U.S. National Institute of Standards and Technology (NIST)
Sensitivity: Typically 30 μA per 100 klux
Linearity: Maximum deviation of 1% up to 100 klux
Response Time: Less than 1 μs (2 m cable terminated into a 604 Ohm load)
Temperature Dependence: ± 0.15% per °C maximum
Cosine Correction: Cosine corrected up to 82° angle of incidence
Azimuth: < ± 1% error over 360° at 45° elevation
Tilt: No error induced from orientation
Operating Temperature Range: −40 °C to 65 °C
Relative Humidity Range: 0% to 95% RH, Non-Condensing
Detector: High stability silicon photovoltaic detector (blue enhanced)
Sensor Housing: Weatherproof anodized aluminum housing with acrylic diffuser and stainless steel hardware; O-ring seal on the sensor base
Size: 2.36 cm Diameter × 3.63 cm (0.93” × 1.43”)
Weight: 24 g head; 60 g base/cable (2 m) with screws
Cable Length: 2 m, 5 m, 15 m, 50 m (6.5’, 16.4’, 49.2’, 164’)
