Range of LightScout Quantum (PAR) Meters
Starting at £350.12 £291.77
PAR is a more valuable measurement than foot-candles as it measures only the light used by plants for photosynthesis.
We offer PAR light meters in variety of configurations for your convenience. Their range is 0 to 2,000 µmol·m-2·s-1 measuring photosynthetically active radiation (PAR) from 400 to 700 nm.
The light that drives photosynthesis in plants is Photosynthetically Active Radiation, or PAR light. This is also referred to as Quantum light, because it is measured in units of moles striking an area over time. Though PAR light ranges from 400 to 700nm, the region brightest to human eyes is the area of least effect on plants. Measuring quantum light can tell you if your plants are getting a sufficient amount of usable light.

| Indoor Unit | 3415F: Accuracy = The Field Scout Light Meters are accurate to ±5%. Cosine correction is accurate to ±3% at 45°, and ±7% at 80°. Quantum Light Meters are calibrated to display PPFD. The meters display PPFD in the range 0-1999 µmol m-2 s-1. 3415FSE and 3415FXSE: Accuracy = The FieldScout Light Meters are accurate to ±5%. Cosine correction is accurate to ±3% at 45°, and ±7% at 80°. 3415FQF: Accuracy = The FieldScout Light Meters are accurate to ±5%. Cosine correction is accurate to ±3% at 45°, and ±7% at 80°. The 3415FQF Quantum and Foot-Candle Meter 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. The meters display values in the range 0-1999. This must be multiplied by 10 to obtain Foot-Candles, so the meter range is 0-19990 Foot-Candles. Since 1 Foot-Candle is equivalent to approximately 10.8 lux, multiplying the meter reading by 108. |
