Traceable® Dual-Range Light Meter Complete
Description
Dual-range Meter reads both lux and foot-candles on a large
1/2-inch-high display. An analog output of 0.1 millivolt per digit
allows readings to be captured by a recorder. Precision selenium
photovoltaic cells and microprocessor provide for a fast-response
sampling rate of 0.4 seconds and an automatic zero adjustment. Display
update rate may be set to 1 or 2 seconds.
To assure accuracy an individually serial-numbered
Traceable® Certificate is supplied to indicate traceability to
standards provided by NIST (National Institute of Standards and
Technology).
Monitor and store results
Unit recalls highest, lowest, and average readings at the touch of a
button. DATA HOLD button freezes the display to capture readings.
Precise photodiode and color-correction filter provide cosine- and
color-corrected measurements.
Readings in lux and foot-candles
Dual-Range Meter 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). Accuracy is ±(5% plus 2 digits).
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. Weight is 10 ounces.
