Art.Nr.: LP-471 P-AProduktbeschreibung
- combined probe LP 471 P-A with two sensors for the measurement of illuminance and UVA irradiance
- destruction-free material measurement according to ISO 3059:2001
general information:
Combined probe for the measurement of illuminance (lux) with photopic standard sensitivity and irradiance (μW/cm2) in the UVA spectral range (315 nm to 400 nm, with peak at 360 nm). Both sensors are equipped with a diffusor for correction according to the cosine law.
Measuring range for illuminance: 0.10 lux to 200·103 lux
Measuring range for irradiance: 1.0 mW/m2 to 2,000 W/m2.
This probe provides a balanced ratio between UVA irradiance and illuminance in μW/lumen (quantity of interest in museums). The probe is equipped with a SICRAM module and 2 m long cable.
application areas:
Museums (see regulation), destruction-free testing (see regulation), for casting and welding control, museum object damage (CIE 157) for paper and wood safety.
