Reads both Lux and foot-candles on a large 1/2-inch-high display. Accuracy is ±5% plus 2 digits. Analog output of 0.1 millivolt per digit allows readings to be captured by a recorder. Precision selenium photovoltaic cells and microprocessor provide a sampling rate of 0.4 seconds and an automatic zero adjustment. Individually serial numbered Traceable® Certificate provides traceability to NIST.
Unit recalls highest, lowest, and average readings. DATA HOLD button "freezes" the display to capture readings. Precise photodiode and color-correction filter provide cosine- and color-corrected measurements. Measures Lux in three ranges: 0 to 1999 (1 Lux resolution), 2000 to 19,990 (10 Lux resolution), and 20,000 to 50,000 (100 Lux resolution). Readings in foot-candles: 0 to 199.9 (0.1 Fc resolution), 200 to 1999 (1 Fc resolution), 2000 to 5000 (10 Fc resolution). Unit is supplied with 2 inch diameter photocell, 40-inch cable, Traceable® Certificate, 9-volt alkaline battery, and recorder output. Size is 6-1/2 x 3 x 1-1/2 inches.
