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 the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA.

Dual displays show lux or foot-candles, or percent differential from a reference point, and the selected light source (daylight, tungsten, fluorescent, or mercury). Traceable® light meter has Serial RS-232 output that allows it to be connected to a computer or data logger for monitoring and keeping results. To assure accuracy an individually serial-numbered Traceable® Certificate is provided from the manufacturer’s ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).

Light meter has an UV wavelength range of 320 to 390 nm. Traceable® Ultraviolet Light Meter measures on three different ranges from 0 to 199.9 µW/cm2 (resolution 0.1 µW/cm2), 1.999 mW/cm2 (resolution 0.001 mW/cm2), and 19.99 mW/cm2 (resolution 0.01 mW/cm2). Accuracy is ±(2% of full scale plus 2 digits). Traceable® Light Meter has serial RS-232 output that allows it to be connected to a computer or data logger for monitoring and keeping results.
