This multifunctional spectral light meter is designed for professionals who require precise and comprehensive light analysis. Equipped with a high-performance spectral sensor, it delivers accurate readings for a wide range of lighting environments.
Unlike traditional lux meters, this device goes beyond basic illuminance measurement. It provides:
Illuminance (Lux / Foot-Candle)
Correlated Color Temperature (CCT: 1000–100000K)
Color Rendering Index (CRI Ra)
UV Index (UVI)
Flicker Frequency & Flicker Percentage
Temperature & Humidity
Perfect for lighting engineers, photographers, workplace inspectors, and researchers.
The dedicated plant mode makes it an ideal tool for:
Indoor farming & vertical agriculture
Greenhouses & hydroponics
Grow light testing
It accurately measures:
PPFD (Photosynthetic Photon Flux Density)
PPFD Blue / Green / Red
YPFD (Yield Photon Flux Density)
Chlorophyll A & B radiation
Helping you maximize plant health, yield, and growth efficiency.
