Light Meters

Product Details :

Fieldscout Quantum Light Meters:

• Manufacturer : Spectrum Technologies Quantum sensors measure light energy at the specific wavelengths plants actually use for photosynthesis. Start taking more meaningful light level measurements yourself with a low-cost quantum meter. Field scout Quantum Meters Measure light used for plant growth.
• Light has three principal characteristics that affect plant growth: quantity, quality, and duration. Light quantity refers to the intensity or concentration of sunlight. Light quality refers to the color or wavelength reaching the plant surface. Light duration or photo period refers to the amount of time that a plant is exposed to sunlight.
• Quantum sensors measure light energy at the specific wavelengths plants actually use for photosynthesis. Research indicates that older lux and foot-candle meters could have error rates up to 45% when used to estimate light quantum available for plant growth. Start taking more meaningful light level measurements yourself with a low-cost quantum meter.
• All quantum meters here measure Photosynthetic Photon Flux (PPF) as µmol m-2 s-1 for Photosynthetically Active Radiation (PAR) in the range of 400 to 700 nm. Quantum meters can be used in the field, laboratory, above or below plants, in growth rooms and greenhouses. The meter approximates radiation between 400 and 700 nanometers(PAR) as umol m-2s-1.

Now also available with external sensor on 2-meter cable.
