Quantum Meters and Sensors

Scientists worldwide are now using high tech quantum sensors to monitor plant lighting. The new quantum sensors measure light energy at the specific wavelengths plants actually use instead of across the whole spectrum as was done previously.  Research indicates that older lux and foot-candle meters could have error rates up to 45% when used to estimate light quantum available for plant growth. Start taking more meaningful light level measurements yourself with one of these new low-cost quantum meters.

Both quantum meters here measure Photosynthetic Photon Flux (PPF) as µmol m-2 s-1 for Photosynthetically Active Radiation (PAR) in the range of 350 to 650 nm.  Quantum meters and sensors can be used in the field, laboratory, greenhouse, garden or home.
