UV Meter

Monitor critical UV rays. This meter measures the UV radiation between 250 and 400 nanometers, and is measured in µmol m-2 s-1 (micromoles of photons per square meter second).
Fieldscout UV Meter monitors critical ultraviolet radiation.
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 photoperiod refers to the amount of time that a plant is exposed to sunlight
High levels of UV light can be detrimental to plants. Use this meter to determine the UV filtering capacity of greenhouse shades and glass barriers. Includes one 9-volt battery. Now also available with external sensor on 2-meter cable.
