This calibrated light meter's ergonomic design allows for one-handed operationClick here to view Light Meter Comparison Chart Features & Applications: This Calibrated Precision Light Meter makes it easy to check light levels in a given area or facility. Featuring an angled sensor on top that allows simultaneous measurement and readout without interference from the operator, the instrument provides precise light level readings, with cosine and photopic correction. The instrument is also equipped with an easy-to-read 33/4 digit LCD that displays units of measure and also low battery indication, and has a data hold function. Features:
Accurately measures ambient illumination in:
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 Light Sensor Silicon photodiode with photopic filter and cosine corrector Diameter 10 mm, angled 70° from display face Temperature Ranges Operation: 32 to 130°F (0 to 55°C) Storage: -4 to 160°F (-20 to 70°C) |
