The Amprobe LM-100 light meter measures the visible light from fluorescent, metal halide, high-pressure sodium or incandescent sources. It is a portable, easy-to-use digital light meter designed for simple one-hand operation reading in Lumen (lux) or footcandle (fc) units. The LM-100 measures a wide range of light up to 20,000 fc or lux with an accurate, high resolution of 0.01 fc/lux.
One lux is the illumination from a one candela lamp perpendicular to a surface one meter squared at a distance of one meter. One fc is the illumination from a one candela lamp perpendicular to a surface one foot squared at a distance of one foot. 1 footcandle = 10.764 lux and 1 lux = 0.09290 footcandles.
Features:
Measure in Lux or Footcandles, front panel switchable
Measuring Range to 20,0000 Lux or Foot candles
Silicon photodiode sensor and filter
Data Hold to freeze reading on the digital display
