The visible light spectrum is the section of the electromagnetic radiation spectrum that is visible to the human eye. When it is measured on the bases of its brightness then it is done with subjective unit’s candles or lux etc. Sper Scientific visible light meters measure luminous flux (Lux), Foot Candle (FC), and LED.
Fast, stable and accurate response
Monitor visible light levels anywhere with fast, stable and accurate response. Results are easily read on the extra large LCD (1" high, 38.1 mm) with bar graph, low battery and over range indications. The color and cosine corrected sensor meets C.I.E. photopic spectrum. Will read LED light. Also features RS232 computer output, min/max, auto power off, external zero adjustment, hold function and a tripod back. The lux / footcandle light meter comes ready to use with a 9V battery, instructions, soft padded case with shoulder strap, and a detachable sensor (with 44" cord) with cover for easier replacement or repair. N.I.S.T. traceable certificate of calibration available.
