SQ-311-SS: Sun Calibration Original Line Quantum with 10 Sensors

$526.00

Apogee line quantum sensors measure a spatial average of PAR (Photosynthetically Active Radiation). The SQ-311 has a sensor bar with 10 sensors and is self-powered with a 0 to 800 mV output. The sensor is calibrated for use in sunlight (Custom electric light calibration is available. Contact Apogee for details). The sensor housing design features an integrated bubble level and is fully potted making the sensor weatherproof. Typical applications include PPFD (Photosynthetic Photon Flux Density) 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.Sensor includes IP68 marine-grade stainless-steel cable connector 30 cm from head to simplify sensor removal and replacement for maintenance and recalibration.
