|Within Vocab||SeaVoX Device Catalogue|
|Preferred Label||Chelsea Technologies 4-pi Photosynthetically Active Radiation sensor HB 071|
|Definition||A submersible instrument designed to measure irradiance over the photosynthetically active radiation (PAR) spectral range. It includes two hemispherical sensors to provide a spherical field of view and uses a logarithmic amplification to provide light measurements over several orders of magnitude. It uses a photodiode with enhanced blue/green sensitivity which, when used in conjunction with blue-tint glass, produces a quantum response that is flat to +/- 3% over the range 450 to 700nm, and 8% at 400nm The instrument has a depth rating of 500m.|
