LS330 Spectral Illuminance Meter

LS330 spectral Illuminance Meter is a versatile instrument designed with a spectral sensor. It is used for measuring illuminance, UV index, flicker frequency, standard deviation of color matching (SDCM), color rendering index (CRI), correlated color temperature (CCT), blue light hazard ratio, temperature, and humidity in various scenarios such as lamps and lanterns lighting, outdoor lighting, greenhouse lighting, and stage lighting. The instrument also can display the spectral curve, which helps identify the type of lighting fixture.

High-precision spectral sensors suitable for human eyes spectrum
The instrument is designed with a spectral sensor, and the spectral response matches the V(λ) function. This ensures accurate measurement precision.

1 million Lx measurement range, suitable for both strong and dim light
Ultra-large range design, range up to 1 million Lx, both strong and dim light can be measured accurately.

Flicker measurement, easily determine if lighting meets requirements
The instrument features a flicker measurement function, can evaluate whether lighting meets requirements based on flicker frequency and percent flicker. This provides reference for sales and R&D of lighting.

Measurement of CCT
The instrument measures correlated color temperature, aiding lighting manufacturers in fixture development and lighting design.

CRI and SDCM measurement
The instrument has CRI and SDCM measurement function, clearly showing the difference between the testing light source and the standard light source.

Display blue light hazard ratio
The blue light hazard ratio can be displayed to objectively evaluate the blue light hazard of the lighting source.
(The blue light hazard ratio is the ratio of the blue light hazard to the corresponding radiation amount. The larger the ratio, the greater the proportion of blue light.)

Spectral curve measurement
The instrument has spectral measurement function, allowing identification of spectral gaps and blue light protection capabilities.

Measure UV index, temperature, and humidity
The instrument also measures environmental parameters such as UV index, temperature, and humidity, making it suitable for evaluating plant lighting sources.
