The MQ-500 quantum meter is the tool of choice for scientists all over the world to accurately measure photosynthetically active radiation from all light sources. It 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.
AM-310 Sensor Wand This accessory incorporates a mounting fixture at the end of a telescopic wand extendable to 33 inches (84 cm) allowing the user to place Apogee sensors in hard to reach areas. The platform features two mounting holes to accommodate both our narrow and wider diameter radiation sensors. This wand is not suited for wet environments.
