Dual displays show lux or foot-candles, or percent differential from a reference point, and the selected light source (daylight, tungsten, fluorescent, or mercury).


An individually-numbered Traceable® Certificate provided with each unit, assures accuracy from our ISO/IEC 17025:2017 (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.


Dual-Display 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 1,999 (1 Fc resolution), 2,000 to 5,000 (10 Fc resolution). For accuracy see chart. Unit has zero reference settings for all light sources.

Precise photodiode and color-correction filter provide cosine- and color-corrected measurements.

Jumbo-sized digits are 1-3/8 inches high. Unit is supplied with 2 inch diameter photocell (cable length is 40 inches), Traceable® Certificate, 9-volt alkaline battery, and computer output. Probe specification is 2-inch diameter photo cell/40-inch cable length. Size is 7 x 3 x 1-1/4 inches. Weight is 9-1/2 ounces. Replacement battery Cat. No. 1112.
