A hard-carbon coating on the outside of the dome smoothes the spectral response and provides extra protection to the silicon surface. The excellent thermal stability of the dome construction and coupling to the instrument body eliminates the need for dome temperature measurements or dome shading.

 

The SGR4 has an internal desiccant that will last for at least 10 years. This minimises maintenance significantly. The interval for dome cleaning can be extended, and the quality of measurements maximised, by fitting SGR4 with the CVF4 ventilation unit.

 

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.

 

Thanks to standardised output and connections of every SGR4, exchanging instruments for recalibration is easy.
