LI-192 maki karkashin ruwa photosynthetic ingantaccen radiation firikwensinAna amfani da shi don auna ingantaccen radiation na photosynthesis a cikin yanayin karkashin ruwa; Siginar da aka auna shine jimlar PAR daga kowane kusurwa a cikin hemisphere. Za a iya aiki a cikin iska (dole ne a kiyaye na'urorin firikwensin bushewa) ko a cikin zurfin ruwa har zuwa 560 m. An gyara na'urar firikwensin ta hanyar cosine kuma sakamakon ma'auni shine photosynthetic quantum flow density (PPFD). Za a iya auna PAR sama da ƙasa a lokaci guda ta amfani da 2009S sinking fixed bracket.

LI-192 yana amfani da silicon photodiode da matattarar gani na gilashi, tare da amsa mai hankali tsakanin 400-700nm, wanda kuma shine kewayon tsawon haske wanda tsire-tsire na karkashin ruwa da algae ke amfani da shi. Matata yana toshe hasken sama da tsawon ruwa na 700nm da kyau, wanda ke da mahimmanci don nazarin hasken karkashin ruwa saboda hasken infrared na karkashin ruwa yana da girma idan aka kwatanta da hasken haske.
