LightScout Quantum Meters - 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.

  •     Measures photosynthetically active radiation (PAR) from 400 to 700 nm
  •     Range of 0 to 2,000 µmol·m-2·s-1
  •     Available in a variety of configurations for your convenience

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.

PAR / QUANTUM LIGHT (400-700nm)
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.

Accuracy
The Field Scout Light Meters are accurate to ±5%. Cosine correction is accurate to ±3% at 45°, and ±7% at 80°.

LightScout Quantum Light Meters are calibrated for sunlight. 

Due to differences in the spectrum generated by artificial lights, the following adjustments must be made in the  value
shown on a sunlight-calibrated meter:

Fluorescent: reads 8% high, so multiply the display by 0.92.
Metal Halide: reads 6% high, so multiply the display by 0.94.
High Pressure Sodium: 0% error—no adjustment needed.
Sunlight: 0% error—no adjustment needed.

Note that the 3415FSE meter displays accurate readings for fluorescent lights when set to “Electric”.
