Apogee SQ-100X-SS Sun calibration quantum sensor, 5 m cable length with connector

Self powered Quantum Sensor for dataloggers and controllers The SQ-100X-SS is a self-powered, analog original quantum sensor with a 0 to 250 mV output. The sensor features a rugged, self-cleaning sensor housing design, and high-quality cable terminating in pre-tinned pigtail leads for easy connection to dataloggers and controllers. 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.
