Overview
The EVERFINE LM-3/2 aiming point luminance meter uses the principle of lens imagery to measure the luminance of Illuminants or objects in a non-contact state through the telescopic Optical inspection system. The LM-3 model has extremely high Sensitivity and High Accuracy, especially suitable for laboratory and verification level measurement; the LM-2 is a single field basic product, and the measurement accuracy meets the national first-class requirements.
Features
1) The LM-3 model features Extremely Sensitivity and High Accuracy, making it particularly suitable for laboratory and validation-level measurements.
2) Select highly stable, Light spectrum Response Linear dispersion and CIE Linear dispersion matching photoelectric detection components to ensure measurement High Accuracy and stability.
3) Multi-field angle switching: LM-3 supports 2 °, 1 °, 0.2 °, 0.1 ° multi-field angle switching, suitable for measurement of different sizes of luminous bodies from small indicators to outdoor LED displays.
4) wide measurement range: to meet the low 0.001cd/m ², up to 4000000cd/m ² luminance measurement.
5) 0.4m~ infinity measurement distance: with a large aperture and high image quality objective lens, it can realize short-distance to long-distance measurement.
6) LM-2 aiming point luminance meter is a single-field basic product, and the measurement accuracy meets the national first-class requirements.
Principle
The luminance meter using the principle of lens imagery, by telescopic Optical inspection system, in a non-contact state, the image of the target object or Illuminant projected onto the photodetector, thereby measuring its luminance.
Applications
Indicator light, instrument panel, outdoor LED display
Steps
1) Select the appropriate measurement field of view (LM-3 model) according to the measurement target size.
2) Adjust the measurement distance (0.4m to infinity).
3) Aim at the target to be measured by observing the field of view.
4) Perform luminance measurements and read data.
Notice
• When selecting the measurement field of view angle, make sure that the size of the target to be measured is greater than the minimum measurement size under this field of view angle.
• Use battery power or Power Adapter (12V/2A) power.
• Can communicate via RS232-C interface.
