Apogee Instruments MQ-500 Full-Spectrum Quantum PAR Features
-
DR BRUCE BUGBEE: Apogee PAR meters have been designed and refined by Dr. Bruce Bugbee, a world-famous crop physiologist.
-
PREMIUM QUALITY: The MQ-500 is preferred by scientists and serious growers for accurate PAR measurements. Our meters stay accurate and reliable while other budget PAR meters can have readings drift by over 50%.
-
FEATURES: The rugged detector measures photosynthetic photons from 400-700 nm from any light source by taking instantaneous or logged measurements.
-
RUGGED DESIGN: The sensor head is made of machined aluminum and fully potted, making it waterproof and rugged. The tangle-free cable facilitates measurements over a large plant canopy, while still allowing the user to view the high-contract display screen.
-
MANUFACTURED IN THE USA: All meters are backed by our four-year warranty and supported by our US-based customer support team.
About Apogee Instruments MQ-500 Full-Spectrum Quantum PAR
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 grown. The meter has a sample and log mode, and will record an integrated daily total in mol m-2 d-1. Sample mode will record up to 99 manual measurements. Log mode will power the meter on and off to make a measurement every 30 seconds. Every 30 minutes, the meter will average the sixty 30 second measurements and record the averaged value to memory. The meter can store up to 99 averages. Once full, it will start to overwrite the oldest measurement with new ones. An integrated daily total will be recorded from the 48 averaged measurements (making a 24 hr period). Sample and log measurements can be reviewed on the LCD display or by downloading the data to a computer, however, the integrated daily total can only be viewed by downloading the data to a computer with the special AC-100 communication cable (a standard USB cable will not work) and ApogeeAMS software.
