Description

3251 Traceable® Dual-Range Light Meter

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.

Traceable® Certificate

An individually-numbered Traceable® Certificate provided with each unit, assures accuracy from our ISO/IEC 17025:2005 (1750.01) calibration laboratory accredited by A2LA.  It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.

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.
