Features
Multi-parameter, wider application
In normal mode, the instrument measures parameters like illumination, CCT, flicker frequency, UV index, SDCM, CRI, temperature, and humidity to evaluate lighting characteristics. In plant mode, it accurately measures PPFD, YPFD, chlorophyll-a, and chlorophyll-b to optimize plant lighting for better quality and yield.
Freely switch between normal and plant modes
The instrument offers both normal and plant illumination modes, meeting diverse measurement needs. It handles both everyday lighting detection and plant growth parameters (e.g., PPFD, chlorophyll content), helping users optimize lighting in various scenarios.
High-precision spectral sensors
The instrument is designed with a spectral sensor, and the spectral response matches the V(λ) function. This ensures accurate measurement precision.
Spectral curve measurement
The instrument has a spectral curve measurement function, which can view the light intensity and distribution at different wavelengths, identify whether the light source has spectral missing and detect whether it has blue light protection.
1 million Lux measurement range, suitable for both strong and dim light
Ultra-large range design, range up to 1 million Lux, 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 CDCM 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.)
Accurately measure photosynthetic photon flux density (PPFD)
The instrument can accurately measure photosynthetic photon flux density (PPFD), yield photon flux density (YPFD) and chlorophyll content, providing comprehensive data support to help optimize plant light intensity, distribution and health status, and improve growth and yield.
