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. This compact light meter is equipped with a silicon photodiode light sensor, with cosine and photopic correction. Its easy-to-read, illuminated, 3 1/4 digit LCD displays light level 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 light reading.

Spec Summary:
Light Level 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
Temperature Ranges
Operation: 32 to 130°F (0 to 55°C)
Storage: -4 to 160°F (-20 to 70°C)
