Full-spectrum Quantum Sensor

Apogee Instrument's full-spectrum quantum sensors/meters provide a research grade measurement of photosynthetically active radiation (PAR), PPF, and PPFD.
Measure photosynthetically active radiation, PAR, in µmol m-2s-1.
Apogee Instruments' quantum sensors provide accurate and cost-effective measurement of photosynthetically active radiation (PAR) from all light sources used to grow plants and corals.
Spectral Response
The full-spectrum quantum sensor has a spectral range of 389 to 692 nm ± 5 nm. The improved spectral response increases the accuracy of LED measurements. The spectral responses can be seen in the graph below.
Graph showing the spectral responses of full-spectrum quantum sensor (spectral range of 389 to 692 nm ± 5 nm).
Accurate, Stable Measurements
Sensors are cosine-corrected to maintain their accuracy when radiation comes from low zenith angles. The sensors measure PPFD with a cosine response accurate within ± 5 % at 75° zenith angle. Long-term non-stability determined from multiple replicate quantum sensors in accelerated aging test and field conditions is less than 2 % per year.
Typical Applications
PPFD measurements 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 PPFD in aquatic environments, including salt water aquariums where corals are grown.
Rugged, Self-cleaning Housing
Patented domed shaped sensor head (diffuser and body) facilitate runoff of dew and rain to keep the sensor clean and minimize errors caused by dust blocking the radiation path. Sensors are housed in a rugged anodized aluminum body and electronics are fully potted.

Ideal for Measurements in Air and Underwater
Apogee quantum sensor are calibrated to make absolute PPFD measurements in air. The waterproof sensors can be used to make absolute PPFD measurements underwater by applying an immersion effect correction factor, the SQ-420, SQ-520, MQ-210, and MQ-510 already apply the correction factor. For details on making underwater measurements, please refer toUnderwater PAR Measurements.
Calibration
To ensure accuracy each sensor is carefully calibrated in controlled conditions and traceable to NIST reference standards. The full-spectrum sensors are pre-calibrated for all light sources.
Mounting
TheAL-120 Solar Mounting Bracket with Leveling Platefacilitates mounting the sensor to a mast or pipe. TheAL-100 Solar Sensor Leveling Plateis designed to level the sensor while sitting on a flat surface or mounting to a surface.
Output Options
Available in multiple analog output options including 0 to 40 mV, 0 to 2.5 V, 0 to 5 V, and 4 to 20 mA ranges. Digital output options include a digital "smart" sensor that uses USB communication and custom software to interface directly to a computer, SDI-12, and Modbus protocols. Sensors are also available attached to a hand-held meter with digital readout. The analog version of this sensor (SQ-500) works with ourµCache Bluetooth Micro Logger.
High Quality Cable
一个IP68 Pigtail-lead传感器特性,marine-gradestainless-steelcable connectorto simplify sensor removal for maintenance and recalibration. Cable is shielded-twisted pair wire with a TPR jacket for high water resistance, UV stability, and flexibility in cold conditions.
Warranty and Support
All Apogee products are backed by an industry-leading four year warranty and outstanding customer support.
