SGR4 Pyrgeometer

The SGR4 has a digital interface and is designed for meteorological observations. The excellent thermal stability of the dome construction eliminates the need for dome temperature measurements or dome shading.

Description

The SGR4 has 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.
