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.
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. For freshwater and saltwater use, we recommend our other wand, the AM-320.
All new for 2020, the Advanced Quantum PAR Meter provides accurate and cost-effective measurement for all light sources used to grow plants. The PHOTOBIO by Phantom Quantum PAR meter is designed to measure PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700nm. There is a proportional relationship between the number of photons absorbed in 400 to 700nm band and the rate of photosynthesis in plants, which is important for horticultural studies and monitoring plant physiology.The Advanced light meter comes complete with a remote sensor, two connection cables, the main unit and easy to replace AAA batteries. The PAR meter can store up to 99 measurements for easy reference.
