The pricing for this model includes a NIST Traceable Calibration Certificate. For the standalone unit without a NIST Certificate, please see the Extech HD450.
The HD450 Light Meter measures from 0 to 40,000Fc and 0 to 400kLux with a 0.01Fc/0.1Lux resolution. Features: 5% accuracy, Peak mode (10µs), Relative mode, Min/Max, Data Hold, backlit LCD display with 40-segment bar graph, and a rugged double molded housing. In addition, the datalogger function can automatically store up to 16,000 readings or manually store/recall up to 99 readings. Comes complete with light sensor with 3ft (1m) cable and protective cover, software with USB cable, hard carrying case and 9V battery.
