©2020 Biological and Chemical Oceanography Data Management Office.A submersible instrument that logs PAR (Photosynthetically Active Radiation), temperature and tilt measurements. Data are recorded on an internal SD card. The sensor is a LI-192 Underwater Quantum Sensor, manufactured by LI-COR. The sensor uses a silicon photodiode and glass optical filters to create a uniform sensitivity to light wavelengths in the 400-700nm range. It measures PAR from all angles in one hemisphere. An anti-fouling wiper is available. The instrument can be configured to record at intervals between 1 and 60 minutes. It is submersible up to 100 metres. PAR measurement accuracy is dependent upon the stability of the sensor pointed towards the water surface.
