Can I use a pyranometer under water?
The CMP series can also be used under water, the depth is limited to 1 meter and can only be used for short measurements. It is advisable not to keep the Pyranometer of the CMP series under water for longer than 30 minutes. The SP Lite (2) and the PAR Lite (2) can be used for a longer period under water, the depth is limited to 2 meters. Please also take “breaking of light on the water surface” in consideration.
