UV Meter - Monitor Critical UV Radiation (250-400 nm) With this Handheld Meter

LightScout UV Meter

• Monitor critical UV radiation (250-400 nm) with this handheld meter
• Determine UV filtering capacity of greenhouse shades and glass barriers
• Range is 0-200.0 µmolm-2s-1 (full sunlight)

Plants can suffer from sunburn exposure to radiation in the mid-ultraviolet part of the electromagnetic spectrum (UV-B) triggers stress responses, inhibition of photosynthesis and DNA damage. As an initial defence, plants produce and accumulate UV-B-absorbing chemical sunscreens, such as flavonoids and sinapate esters to block low-dosage UV-B.

A UV meter can help detect if your plants are being exposed to high levels of detrimental UV radiation, and to check the effectiveness of UV filtering materials. In general, a UV meter will measure the quantity of light in the 250-400nm range. Specific meters are also available for individual UV ranges.

UV-C light (200-280nm) can kill your plants. Fortunately, it is absorbed by ozone in the stratosphere.
UV-B light (280-315nm) is harmful as well and can cause plant colour to fade.

UV-A light can be subdivided into two bands. The 315-380nm band has no effect on plant growth, while the 380-400nm band begins the range for photosynthesis.)

Accuracy

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

Calibrated to display the intensity of ultraviolet light in the 250-400 nm wavelength range in units of µmol m-2 s-1 (the number of photons in units of micromoles, striking an area one meter square each second). The meter displays 0-199.9 µmol m-2 s-1.
