Product Description

Product Description

The meter is a precise instrument for measuring visible light emitted from fluorescent lamp, metal halide lamp, high-pressure sodium lamp or incandescent lamp, LED lamp, and the like.

Illuminance is a unit of illumination intensity. It represents luminous flux per unit area in physics -- lumens per square meter (Lm/m²), also known as Lux (1 Lux = 1 Lm/m²), wherein Lm is the unit of luminous flux, and Lux is the unit of illuminance.
As for "V (λ) matching error", it is known to all that light source of different colors has different color temperature in practices, and even white light source has warm white and cold white with different color temperatures. In this way, light meter of low "V (λ) matching error" is necessary to ensure higher "accuracy" in the detection of light source of different color temperatures. Professional light meter enjoys the advantage of low-level "V (λ) matching error" and satisfies the CNS 5119 Class II standard.
I. Product Features
1. Resolution up to 0.01 Lux makes it possible for detecting dim light and weak light.
2. Low-level V (λ) matching error (ƒ'1≤6%) complies with the CNS 5119 Class II standard.
3. It has a wide measuring range of 0.01 Lux to 39990 Lux.
4. It is capable of peak holding and data retention.
