LM-120
Light Meter with Auto
Ranging
The Amprobe LM-120 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-120 measures
a wide range of light up to 20,000 fc or 200,000 lux with
an accurate, high resolution of 0.01 fc/lux. This unit is
Autoranging plus manual ranging with ability to Zero out the
reading before taking a measurement.
Use the LM-120 light meter to measure the illumination level
in the interior and to switch off or reduce or increase the
output level of lighting fixtures. Reduce the energy burden
of the building by significantly increasing the efficiency of its
lighting system.
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 foot-candle = 10.764 Lux and 1 lux = 0.09290
