SQ-204X-SS: Sun calibration quantum sensor
Amplified 4-20mA output, 5m cable length with connector
The SQ-204X-SS is an amplified original quantum sensor with a 4 to 20 mA output. The sensor was designed for use in environments with significant background electrical noise that can be found in many industrial applications. 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. Quantum sensors are also used to measure PAR (Photosynthetically Active Radiation)/PPFD in aquatic environments, including salt water aquariums where corals are grown. Sensor includes IP68 marine-grade stainless-steel cable connector to simplify sensor removal and replacement for maintenance and recalibration.
