SQ-110 Sun Calibrated PAR Sensor
The SQ-110 is a self-powered quantum sensor that measures photo-synthetically active radiation and is calibrated for use in sunlight. The sensor housing design features a fully potted, domed-shaped head making the sensor fully weatherproof and self-cleaning.
Photo-synthetically active radiation (PAR), or photosynthetic photon flux (PPF), is the wavelength range from 400 to 700 nanometers and is strongly correlated with plant growth. Gardeners, greenhouse managers, growth chamber users and salt-water aquarists measure PAR to ensure optimal specimen health.
The SQ-110 can be used in combination with a LINPAR Linear PAR Sensor and LSM1 Light Sensor Meter for complete monitoring of the plant canopy light environment.
The SQ-110 is installed above the plant canopy to measure ambient light conditions and one or more LINPAR sensors are installed within or beneath the canopy. This way leaf area index or the fraction of absorbed radiation can be monitored.
