LP NET 14 is a 4-component net-radiometer for the measurement of the net
radiation between 0.3μm and 45 μm.
The net-radiometer consists of two pyranometers (one for the measurement of
the global radiation Esw↓ and the other one for the measurement of the reflected
solar radiation Esw↑) and a pair of pyrgeometers (one for the measurement of
the infrared radiation emitted by the sky EFIR↓ and the other one for the infrared
emitted by the ground surface EFIR↑).
The LP NET 14 is equipped with a temperature sensor (NTC). The measurement
of the temperature is needed for the measurement with the two pyrgeometers,
in fact, the far infrared is derived by measuring the thermopile output and by the
knowledge of the instrument’s temperature.
The net radiometer is suitable for outdoor use in all weather conditions and
requires little maintenance.
