Spectrum 3415FQF LightScout Quantum/Foot-Candle Meter

- Measure the light used for plant growth; PAR is a more valuable measurement than foot-candles as it measures only the light used by plants for photosynthesis.
- Measures both PAR light, and light intensity as perceived by the human eye. The eye perceives light of approximately 560 nm most strongly, with perception half that at 500 and 600 nm (* must multiply by 10 to obtain Foot-Candles, so meter range is  0-19990 Foot-Candles)
- Range; 0 to 2000 µmol·m-2·s-1, accurary of ±5%; Cosine correction is accurate to ±3% at 45°, and ±7% at 80°
