These Extech Instruments Light Meters are easy-to-operate and features a large 1/2" LCD display. It provides light measurements in either foot-candles or lux. A precision selenium photocell probe and microprocessor provide 5% accuracy and either fast (1 second) or slow (2 second) sampling time.
The 1 mV-per-count analog output can be used to capture readings to a recorder. Each meter includes RS-232 outputs and 9 V battery.
Displays measurements in either foot-candles or lux over 3 ranges
Uses precision photo diode and color correction filter to ensure accuracy
