LP 471-P-A, Probe for Illuminance and UVA Irradiance

Application:
This probe is an optional accessory for the Photo-Radiometer HD 2302.0.
It is a combined probe for measuring illuminance (lux), with standard photopic response, and irradiance (µW/cm²) in the UVA spectral range (315 ... 400nm, with peak at 360nm).
Both the sensors are equipped with a diffuser for the correction according to the cosine law.
This probe provides the ratio between UVA irradiance and illuminance in µW/lumen (quantity of interest in museums). The probe is equipped with a SICRAM module and a 2m cable.
