Product Description

The MQ-200 has a hand-held meter, attached via cable, that displays and stores measurements. The sensor head features a fully potted, domed-shaped design making it fully waterproof, weatherproof and self-cleaning. 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.
