cal-Light 400L Calibrated Precision Light Meter with NIST Certificate Item #: Q533 Manufacturer: The Cooke Corp. Product Type: Digital Light Meters Your Price: $495.95 In Stock |
This calibrated precision Digital Light Meter's ergonomic design allows for one-handed operationFeatures & 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. Features:
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) |
