LP PHOT 02 Photometric probe.

Model  Description 
LP PHOT 02  Photometric probe for measuring ILLUMINANCE
LP UVA 02  Radiometric probe. IRRADIANCE in the range of UVA.
LP UVB 02  Radiometric probe. IRRADIANCE in the range of UVB.

LP PHOT 02 probe measures illuminance (lux), defined 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 V(λ).
The difference in spectral response between LP PHOT 01 and the standard photopic curve V(λ) 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 .

The LP UVA 02 radiometer measures the broadband UVA irradiance on a plane surface (Watt⁄ m2).
Measured irradiance is the result of the sum of direct solar irradiance and of diffuse irradiance.
The radiometer can measure the UVA irradiance in closed room too.
