APOGEE MQ500 QUANTUM METER WITH FULL SPECTRUM SENSOR (400-700 nm) APOGEE INSTRUMENTS

Apogee MQ500 Quantum Meter with Full Spectrum Sensor (400-700 NM) by Apogee Instruments is designed to accurately measure photosynthetically active radiation. This device is chosen by scientists worldwide for its reliability and precision. The meter is portable and connects via cable to display and store measurements.

The sensor uses a silicon photodiode enhanced by blue light. Additionally, it features custom optical filters. The sensor housing design is robust and self-cleaning. The body is made of anodized aluminum with an acrylic diffuser. Typical applications include measuring PPFD in outdoor environments, greenhouses, and growth chambers.

The meter can record reflected or under-canopy PPFD measurements. This makes it useful in aquatic environments, such as saltwater aquariums. The device has a sampling and logging mode. It records a daily integrated total in mol m-2 d-1.

The Sample mode allows for up to 99 manual measurements. The Log mode turns the device on and off to take a measurement every 30 seconds. Every 30 minutes, it calculates the average of sixty 30-second measurements and records the average value in memory. It can store up to 99 averages.

When the memory is full, it starts overwriting the oldest measurement. A daily integrated total is recorded from the 48 average measurements. Measurements can be reviewed on the LCD display or by downloading data to a computer. However, the daily integrated total can only be viewed by downloading the data.

Downloading requires the AC-100 communication cable. A standard USB cable will not work. The ApogeeAMS software is necessary for data download.
