Description
SGR4 Pyrgeometer from Kipp and Zonen
The SGR4 pyrgeometer is the highest quality pyrgeometer available. It is designed to measure downward longwave radiation. It has a RS-485 Modbus® interface, amplified analogue output, improved response time and temperature corrected measurement data.
The long-wave net- and downward radiation are directly available over Modbus®.
The wide and low power supply range from 5 to 30 VDC makes integration in meteorological and solar energy stations easy. The SGR4 is extremely robust and comes with 5 years warranty.
