Spectrum 3415FXSE LightScout Dual Solar/Electric Quantum 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.
- Uses an external light sensor for hard-to-reach places; comes with 1m (3 ft) connecting cable
- Measures photosynthetically active radiation (PAR) from 400 to 700 nm
- Range; 0 to 2000 µmol·m-2·s-1, accuracy of to ±5%; Cosine correction is accurate to ±3% at 45°, and ±7% at 80°
