NET IRRADIANCE METER, Model : LP NET 14, Brand : DeltaOhm

LP NET 14 is a 4-component net-radiometer for the measurement of the net radiation between 0.3¼ m and 45 ¼ m. 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.
