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-2d-1。样本模式最多可记录99个手动测量。日志模式将仪表电源开启/关闭以每30秒进行一次测量。每30分钟仪表将平均六十六次测量，并将平均值记录到内存中。仪表可以存储多达99个平均值，一旦完整就会开始覆盖最古老的测量。将从48个平均测量（制作24小时）中记录集成的日常总量。可以在LCD显示屏上介绍样本和日志测量，或者通过将数据下载到计算机，但是，只能通过将数据下载到计算机来查看集成的日常总数。将数据下载到computerrequires theAC-100通信电缆（标准USB电缆不起作用）和ApogeeAMS software。
For a limited time, when purchased on our website from inside the USA, the meter comes with free shipping and a free neoprene carrying case (a $12 value).
For instructions on how to use the meter for underwater measurements, see this page for the浸没效应校正因子或考虑购买MQ-510。

mq - 500是一个完整的spectrum quantum sensor with a spectral range of 389 to 692 nm ± 5 nm, which can be seen in the graph below. This improved spectral response of this new meter increases the accuracy of LED measurements when compared to our previous original models.
MQ-500用于测量室外环境，温室，生长室和水族馆的输入PPFD测量。
