UVA - UVB Radiometer (Irradiance Meter) from Delta Ohm

UVA Radiometer (Irradiance Meter)

LP PHOT 02 probe measures illuminance (lux), defi ned as the ratio between the luminous flux (lumen) passing through a surface and the surface area (m2).

The spectral response curve of a photometric probe is similar to the human eye curve, known as standard photopic curve. The difference in spectral response between LP PHOT 01 and the standard photopic curve is calculated by means of the error f1’.

It has been designed for long-time outdoor installation. The photometric measurement probe designed for outdoor readings, is basically used for taking weather and climate measurements during daylight.

UVB Radiometer (Irradiance Meter)

The LP UVB 02 radiometer measures the global irradiance in the UVB spectral region on a plane surface (Watt/m2). In particular, the instrument’s spectral sensitivity is centered at 305nm with a 5nm band width (FWHM). The global irradiance is the sum of the direct solar irradiance and the sky diffuse irradiance on a surface parallel to the ground. In contrast to the visible spectrum where the direct
component prevails over the diffuse component, in the UVB spectral region light is strongly diffused by atmosphere and thus the two components are equivalent.

Therefore it is of primary importance for the instrument to be capable of measure both components accurately. The LP UVB 02 probe is typically used in the following sectors:
• Monitoring the ozone layer. Indeed, the radiation around 295nm – 315nm is strongly absorbed by ozone located in the stratosphere, therefore each small variation of the ozone layer corresponds to an increase or decrease of the UV radiation reaching the ground.
• Effects of UVB radiation (the most harmful to human health) on living beings.
• UVB radiation measurement in work spaces.
