COMPACT-LW ALW-CMP
- ■Description
- COMPACT-LW is an autonomous deployable data logger for PAR (Photosynthetic Available Radiation: 400 to 700nm) measurements. The instrument has a wiper to inhibit biological growths on the optical window over the deployment period. It has a cosine collector as the PAR sensor. The cosine and filter characteristics of the sensor are ideal for PAR measurement.
