Biospherical GUV-2511 Ground Based UV/PAR radiometer
|Within Vocab||SeaVoX Device Catalogue|
|Preferred Label||Biospherical GUV-2511 Ground Based UV/PAR radiometer|
|Definition||A multiwavelength ground-based radiometer system designed to measure solar ultra-violet (UV) irradiance and Photosynthetically Active Radiation (PAR) for long-term monitoring applications. It can also be used to measure cloud optical thickness and total column ozone. It features powder-coated aluminium housing which may be mast-mounted, as well as specialised low-noise sensors with optimised interference filters. An internal sensor also measures photodiode array temperature. It uses RS-232 serial output for connection to a PC, and may be deployed individually or in networks. The GUV-2511 replaced the GUV-511 in 2003, and was retired in 2017. The GUV-2511 measures UV irradiance over 6 wavebands: 305; 313; 320; 340; 380 and 395 nm. It measures PAR from 400-700nm. It as a standard FWHM bandwidth of 10 nm with an optional FWHM bandwidth of 20 nm. The temperature coefficient of the dark signal is less than +/- 3 uvolts per degC.|
