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 provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

DATA HOLD button freezes the display to capture readings. Precise photodiode and color-correction filter provide cosine- and color-corrected measurements.

  • Display update rate 1 or 2 seconds
  • Reads in both lux and foot-candles
  • Color- correction filter

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. Replacement battery Cat. No. 1112.
