This is our quantum sensor and line quantum sensor, designed for use with dataloggers. Line quantum sensors are often used to quantify the variable light in greenhouses and below plant canopies because they provide a spatial average.
An innovative blue lens improves the accuracy of these sensors. The pigments in the lens filter incoming light for an improved spectral response.
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.
