Apogee MQ-500 Quantum PAR meter - BUNDLE
This bundle contains the following:
- 1 x Apogee MQ-500 Quantum PAR meter
- 1 x Official Apogee Neoprene Protective Carry Case
- 1 x Apogee Wand (of your choice)
A high-quality, robust and effective quantum sensor for measuring light intensity levels. The MQ-500 is a 'full-spectrum' option (389 to 692 nm ± 5 nm) and our 'go-to' sensor; recommended for both hobbyists and professionals alike.
Apogee are quickly becoming well known and respected in the industry for manufacturing - amongst other laboratory-grade measuring equipment - high-quality, extremely accurate horticultural lighting sensors. Whether you're a hobby grower or a large scale professional, we've got you covered with a fantastic range of Apogee Sensors to fit every grower's requirement.
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 aluminium 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.
How is the MQ-500 different to the original Apogee sensors?
The MQ-500 is a full 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.
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/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. Downloading data to a computer requires the AC-100 communication cable (a standard USB cable will not work) and ApogeeAMS software
This product comes with a 4 year replacement Warranty from the date of purchase. Rest assured that if your product does develop a fault during this period, it will be replaced at our expense (from UK stock) ASAP. If a replacement isn't available, a full refund will be offered.

Apogee Neoprene Protective Pouch - AA-090
This Official Apogee 5" x 8" x 1" (12.7 x 20.3 x 2.5cm) zippered neoprene pouch is great for safely storing Apogee meters, microCache devices, and sensors. Water resistant.
Apogee PAR Meter Sensor Wand (AM-310)
The original, Apogee telescopic sensor wand. An easy to transport, easy to use tool for extending your sensor's reach.
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.
Apogee PAR Meter Sensor Wand (AM-320)
This is a completely waterproof, screw-pole sensor wand and is the longest version available at 102cm.
This accessory incorporates a mounting fixture at the end of a 40 inch (102 cm) segmented fiberglass wand and is well-suited for fresh and saltwater use. The wand unscrews into three sections for easier storage and transport. All radiation sensors are compatible with the wand, which allows the user to place the sensor in hard to reach areas such as in aquarium tanks and greenhouses.
What's in the box?
