Amprobe LM100 Light Meter
Designed for comprehensive evaluation of visible light from various sources, the Amprobe LM100 Light Meter is ideal for measuring light no matter what the application.
Capable of both footcandle and lux measurements, the Amprobe LM-100 also includes the ability to accurately determine light from flourescent, metal halide, high pressure sodium and incandescent sources with high accuracy and resolution. When measuring it can detect light up to 20000fc and 20000lux with general resolution of 0.01fc/lux.
This product allows the user to carry out extensive evaluation of an environment to detect that light output is comfortable and energy efficient. By evaluating interiors with the LM-100 it is easy to determine if too much energy is being output and it can be used to increase the overall efficiency of lighting systems within that property.
To carry out measurements the LM-100 uses a precise photodiode silicon sensor and filter to accurately determine the light level. This is equipped to the main unit via a flexible cable to ensure it can be easily positioned in a certain area to get the best reading.
