    Description

    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.

    Technical data Illuminance:
    Measuring ranges (lux): 0.10  ... 199.99  ... 1999.9  ... 19999  ... 199.99·103
    Resolution (lux): 0.01     0.1     1     10
    Spectral range: in agreement with standard photopic curve V(lambda) 
    alpha (temperature coefficient)  f6 (T): <0.05 % K
    Calibration uncertainty: <4 %
    f'1  (in accordance with photopic response V(lambda)): <6 %
    f2 (response according to the cosine law): <3 %
    f3 (linearity): <1 %
    f4 (instrument reading error): <0,5 %
    f5 (fatigue): <0,5 %
    Class:  B
    Drift after 1 year: <1%
    Working temperature: 0 ... +50°C
    Reference standards: CIE n. 69 - UNI 11142

    For the illuminance spectral response please refer to the curve of the LP-471-PHOT probe.

    Technical data UVA irradiance:
    Measuring range (W/m²): 1.0·10-3 ... 999.9·10-3

                                     20.00 ... 199.99
                                     200.0 ... 1,999.9
    Resolution (W/m²):   0.1·10-3 /  0.001 / 0.01 / 0.1
    Spectral range: 315 ... 400nm (peak at 360nm)
    Calibration uncertainty: <5%
    f2 (response according to the cosine law): <6%
    f3 (linearity): <1%
    f4 (instrument reading error): ±1 digit
    f5 (fatigue): <0.5%
    Drift after 1 year: <2%
    Working temperature: 0 ... +50°C
    Probe head dimensions: Ų30mm x 38mm

    For the UVA irradiance spectral response please refer to the curve of the LP-471-UVA probe.
