This calibrated precision Digital Light Meter's ergonomic design allows for one-handed operationClick here to view Light Meter Comparison Chart Features & Applications: This Calibrated Light Meter is a user-friendly device equipped with a silicon photodiode light sensor, with cosine and photopic correction. The instrument also features an angled sensor on top that allows simultaneous measurement and readout without interference from the operator, and a 3 1/4 digit LCD that displays light level units of measure and low battery indication. Features:
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) |
