COM INED PRO E LP471P-A
LP471P-A is a two sensors combined probe with SICRAM module for measuring
illuminance (lux) with standard photopic spectral response and irradiance (μW/cm2)
in UVA spectral range (315...400 nm, with peak at 365 nm). he probe also provides
the ratio of UVA irradiance and illuminance in µW/lumen (quantity of interest in the
museums field).
Equipped with diffuser for the correction according to the cosine law.
At switching on, the instrument displays alternatively the measures of the two
sensors. Pressing any key (except ON/OFF), automatic commutation is turned off. o
reactivate it, press HOLD and REL keys together.
o select the measure to display, press UNI key.
COM INED PRO E LP471A-UVEFF
LP471A-UVeff is a two-sensors combined probe with SICRAM module for measuring
total effective irradiance according to the UV weighting curve. wo sensors are
used to correctly measure the total effective irradiance in the range 250...400 nm.
Both sensors are equipped with diffuser for the correction according to the cosine law.
he probe provides the total effective irradiance (“Er” at display), the effective
irradiance in the range UV-CB (“BC” at display) and the UVA irradiance (“A” at display).
At switching on, the instrument displays alternatively the measures of the two
sensors. Pressing any key (except ON/OFF), automatic commutation is turned off. o
reactivate it, press HOLD and REL keys together.
o select the measure to display, press UNI key.
PRO ES LP471PYRA10 - LP471PYRA02 – LP471PYRA03
he LP471PYRA… probes measure the global solar radiation in the spectral range
283…2800 nm (LP471PYRA10 and LP471PYRA02) or 300…2800 (LP471PYRA03).
hey are composed of a pyranometer (LPPYRA02, LPPYRA03 or LPPYRA10) and a cable
with SICRAM module.
Since calibration data of pyranometer are saved in SICRAM module, the cable cannot
be used together with other pyranometers.
he global solar radiation is expressed in W/m2 or μW/cm2. Measuring range is
0…2000 W/m2.
No user calibration is required.
PRO E LP471SILICON-PYRA
he LP471SILICON-PYRA probe measures the global solar radiation using a
silicon photodiode in the spectral range 400…1100 nm.
he particular geometry and the diffuser allow the sensor to have a field of view of
180° according to the cosine law.
he probe is suitable for the measurement of natural sunlight. Under overcast skies,
or for reflected light measurements the use of a thermopile pyranometer is
recommended (LP471PYRA10, LP471PYRA02 or LP471PYRA03).
he measurement of global solar radiation is expressed in W/m2 or μW/cm2.
Measuring range is 0…2000 W/m2.
No user calibration is required.
