SXQ Quantum Light Sensor & Spectrometer
SXQ quantum light and spectrum sensor: PPFD, lux, color temperature, flicker and spectral intensity in one compact, weather-proof package.
PPFD, DLI and Color Spectrum
The SXQ quantum light and spectrum sensor gives precise, real-time data on the light quality and energy delivered to your crop.
It measures light intensity in lux and ePAR PPFD, color temperature and relative spectral intensity in one compact package.
Control Your DLI
Manage supplementary lighting and more from accurate canopy measurements to control your daily light integral (DLI). A rugged design and low cost let you mount the sensors permanently in the growing environment.
- The same PPFD data as popular quantum light meters.
- Standard PAR (400 to 700 nm) or extended PAR (400 to 750 nm) calculation.
- A full spectral intensity plot shows the composition of your light.
- Weather-proof enclosure for indoor or outdoor mounting, with outdoor-rated cable.
- Bracket included for a pole or flat surface.

Floor Stands
Agriculture-grade floor stands give a rugged, adjustable way to mount sensors in the canopy, on the floor or directly on table trays. Corrosion-resistant construction with a stable all-stainless-steel base, in three heights.
