Net Radiometer (SN500SS)
Digital, Lowcost Net Radiometer
The SN500SS Four-Component Net Radiometer by Apogee Instruments measures upward and downward shortwave and longwave radiation individually for accurate net radiation monitoring. Its SDI-12 digital output reduces the need for multiple analog inputs, simplifying installation. The package includes the sensor, mounting rod, pigtail cable for data logger connection, and a protective carrying case.
