LIGHT METER – Traceable® Dual-Range Light Meter
Catalog No. 3251
• Display update rate 1 or 2 seconds
• Reads in both lux and foot-candles
• Color- correction filter
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.
Monitor and store results
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). For accuracy see chart. 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.
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from Control Company ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
