Combined probe for measuring ILLUMINANCE (lux), with standard photopic response, and IRRADIANCE (μW/cm²) in the UVA spectral range (315…400 nm, with peak at 360 nm).
Both the sensors are equipped with diffuser for the correction according to the cosine law.
- Illuminance measuring range: 0.10 lux … 200·10³ lux.
- Irradiance measuring range: 1.0 mW/m² … 2000 W/m².
This probe provides the ratio between UVA irradiance and illuminance in μW/lumen (quantity of interest in museums). CIE 157.
Supplied with SICRAM module and 2 m cable.
The probe works with the instruments DO9847 (from rev. R.1), HD31, HD2302.0 (from rev. 01), HD2102.1 (from rev. 11) and HD2102.2 (from rev. 21).
