LM-50KL 1. Description Measures light from visible luminaries equipped with white light LED, fluorescent, metal halide, high-pressure sodium and incandescent sources. 2. Accessories 1 1 1 1 3. Meter 9 Volt battery Manual Carrying Case Safety Precaution CAUTION Be extremely careful for the following conditions while measuring Do not operate the meter under the environment with explosive gas (material), combustible gas (material) steam or filled with dust.
LM-50KL 4. Preface The flux of light received in a unit area of a certain side being shown is popularly known as illumination. The measuring unit in both United Kingdom and America is known as footcandles light, but in Europe it is also known as meter candlelight. One foot-candles light is the illumination of light that falls on one side which is one foot away from a one foot-candlelight and exactly intersecting with the light.
