Traceable® Dual-Display Light Meter
By Control
Two displays show lux or foot- candles and the selected light source (daylight, tungsten, fluorescent, or mercury). Accuracy is ± (4% full scale plus 2 digits). Unit has zero reference settings for four light sources: tungsten, fluorescent, daylight, and mercury.
Connect to computer or data logger
Traceable® light meter has Serial RS-232 outputs that allows it to be connected to a computer or data logger for monitoring and keeping results. Individually serial-numbered Traceable® Certificate is provided to indicate instrument traceability to NIST.
Readings in lux and foot-candles
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 1999 (1 Fc resolution), 2000 to 5000 (10 Fc resolution).
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. Light meter displays percent differential from a reference point.
Jumbo-sized digits are 1-3/8" high. Unit is supplied with 2" diameter photocell (cable length is 40"), Traceable® Certificate, 9-volt alkaline battery, and serial computer output. Size is 7 x 3 x 1-1/4". Weight is 9.5 ounces. Replacement battery Cat.No. 291-1112.
