TA636A Digital Lux Meter Broad measurement range: measures illuminance from 0.1 lux up to 200000 lux (0.01 fc to 20000 fc), suitable for a wide range of lighting conditions. precision probe: silicon photodiode probe with filter lenses, providing accurate readings with an incidence angle of 120 degrees. Flexible unit switching: easily switch between LUX and FC units using the Changan UNIT key for workflow flexibility. Max and min value display: quickly view the maximum and minimum illuminance values during a measurement session for reliable scene assessment. Practical reliability: designed to deliver consistent illumination measurements across varied environments and lighting designs. Use scenarios Photography and videography: verify lighting levels to achieve correct exposure, contrast, and color balance for shoots. Interior and architectural lighting design: assess and document lighting levels in offices, showrooms, galleries, and other spaces to meet design and compliance targets. Horticulture and greenhouse management: monitor daytime and artificial lighting to optimize plant growth cycles and light utilization. General workspace safety and efficiency: confirm adequate illumination for work tasks and ergonomic comfort across different areas.
