Features & Applications:
Checking light levels in a given area or facility improves its safety and saves on wasted energy. This unique, user-friendly light meter features an angled sensor on top that allows simultaneous measurement and readout without interference from the operator.
Be assured of precise light level readings, as this meter is equipped with a silicon photodiode sensor, with cosine and photopic correction. Its easy-to-read 33/4 digit LCD displays units of measure and low battery indication. With a quick flip of a switch, choose between Footcandle and Lux; then simply press the button to take and hold your reading.

Spec Summary:
Light Measuring Range
Autoranges 0.1 fc or lux to 40,000 fc or lux
Units
Choose fc or lux with user selectable switch located in battery compartment
Accuracy
a) Intensity linearity: 2%
b) Photopic: Better than 1.0% of CIE curve
c) Cosine error: Less than ±1.0% up to an incident angle of ±85°
d) Overall accuracy ±5% of displayed value
Calibration
Light calibrations and recalibrations are performed by COOKE and are traceable to NIST Standards. The photopic response of the calibrated sensor matches the CIE standard observer curve response to within 1% of the reading when using a standard tungsten source at 2856°K
