Beha-Amprobe LM-120 Light Meter
Determine the amount of visible light coming from a light source with the Beha-Amprobe LM-120.
Suitable for use with fluorescent, metal halide, high-pressure sodium and incandescent light sources, the LM-120 includes a light sensor attached to the main meter via a flexible cable. The light sensor should be held as close to the source as possible to gain a reading.
Amprobe LM-120 Light Meter
Light levels can be measure up to 20,000 footcandles (FC) or 200,000 lux with accurate high resolution of 0.01FC/lux. The LM-120 includes both auto and manual ranging modes, plus a zeroing mode which ensures accuracy before measurements taken place.
Want to jot down a reading? Hit the data hold button to instantly freeze the current value on the screen. A dedicated mode for calculating the maximum/minimum light levels over a period of time is also included.
