apogee instruments Art.Nr.: 1507128

The MQ-500 has a hand-held meter, attached via cable, that displays and stores measurements. The sensor incorporates

a blue-enhanced silicon photodiode and custom optical filters with a rugged, self-cleaning sensor housing design, anodized

aluminum body with acrylic diffuser.

Typical applications include PPFD measurement over plant canopies in outdoor environments, greenhouses, and growth chambers

and reflected or under-canopy (transmitted) PPFD measurements in the same environments. Quantum sensors are also used to

measure PAR/PPFD in aquatic environments, including salt water aquariums where corals are grown.
