The SpotOn Quantum PAR Light Meter from Innoquest is a scientifically accurate instrument that takes readings from any source, including LEDs. Photosynthetic Active Radiation (PAR) is the best measure of the quantity of photosynthetic light that is reaching the surface of the plant and is measured in micromoles per meter squared per second.
The SpotOn Quantum PAR Light Meter takes PAR readings about once per second. The meter’s software automatically stabilizes readings from 50 or 60 Hz light sources. To obtain an average reading for a lighted area you need only press and hold the SCAN button and wave the meter throughout the area where you want to obtain the reading.
