Quantum (PAR) Sensors / Meters

Research grade measurement of photosynthetically active radiation (PAR), PPF, and PPFD
Apogee Instruments Quantum sensors are a trusted standard for measuring photosynthetically active radiation by agricultural professionals all over the world. We offer four types of quantum sensors; the Full Spectrum (blue head), the Original (black head), the Extended Range PFD (silver head), and a Quantum Light Pollution Sensor.
OurFull-spectrum Quantum Sensorsfeature an advanced optical detector that provide high-accuracy PAR measurements (400-700 nm) under all light sources, including all modern colored LEDs. OurOriginal Quantum Sensorsfeature a less expensive optical detector that is excellent for measuring broadband light sources, but less accurate when measuring certain LED colors. Our newExtended Range PFD Sensorsmeasure 340-1040 nm for the newest LED fixtures with UV and far-red wavelengths beyond traditional PAR. Our newQuantum Light-Pollution Sensorsare highly sensitive to detect low-level stray photons in the 340-1040 nm range that can disrupt plant dark periods in sensitive plants. Apogee also offers a variety of meters and packages to measuredaily light integral(DLI).
Click each of the four sensor lines below to learn more. For Apogee's new 2-band sensors that measure PAR and Far-red,bob 体育 app .
Full-Spectrum Quantum Sensors

Light Source
Provides accurate PAR measurements under all light sources, including LEDs.

Spectral Range
400 to 700 nm ± 5 nm (wavelengths where response is greater than 50 % of maximum)

SQ-500 full-spectrum quantum sensor spectral response graph.

Output Options
Available in multiple analog and digital outputs including unamplified, SDI-12, Modbus communication protocols, attached to a hand-held meter with a digital output, as a "smart" sensor that uses USB communication and custom software, or with Apogee's new microCache device.
