The SGR3 longwave radiation meter is designed for use in the field of meteorological measurement, measuring downward atmospheric longwave radiation. It adopts a specially designed silicon window. The internal sun blind filter can block solar radiation. The CGR3 data represents the radiation exchange across the entire hemisphere, as the reference SGR 3 instrument is calibrated based on the reference CG4 instrument within an outdoor 180 degree viewing angle range.
SGR3 is equipped with a Modbus ® The interface and analog output signals have been amplified and processed, and the response time has also been improved. The measurement data is temperature corrected. Through this interface, long wave net radiation and downlink radiation data can be directly obtained. SGR3 has a wide power range and low supply voltage, between 5-30VDC, making it easy to integrate with meteorological stations and solar power plants. Its design is extremely sturdy and reliable, with a 5-year warranty (*). The base of the instrument has mounting holes, a bubble level, and leveling feet for precise leveling. For the convenience of installation, replacement, and recalibration, the instrument also has a weatherproof connector. The temperature dependence and directional response characteristics of SGR3 have been improved, making it an ideal choice for meteorological and agricultural applications. Due to the standardized output and connectors used in each SGR3, you can easily exchange instruments for recalibration. The standard components provided include SmartExplorer Windows for recording data ™ Software, data display screen, and Modbus ® Address setting module.
