Product Description
Apogee SQ-520 sensors are calibrated through side-by-side comparison to the mean of four transfer standard sensors under a reference lamp. The reference sensors are recalibrated with a quartz halogen lamp traceable to the National Institute of Standards and Technology (NIST).
Precision Light Measurement for PAR ApplicationsDesigned specifically to measure Photosynthetically Active Radiation, the SQ-520 delivers reliable, high-accuracy readings across a broad 0-4000 mol m2 s1 range. Its digital USB interface and advanced silicon-celled photodiode allow precise monitoring, essential for optimizing plant growth environments.
Rugged, Weatherproof, and FlexibleWith its UV-stable polycarbonate construction and IP68 waterproof rating, the sensor operates reliably in challenging field conditions, greenhouses, and laboratories. Its wide operating and storage temperature range, plus a standard 2-meter cable (extendable to 30 m), offer versatile installation options.
Simple Integration and Data ManagementThe sensor is plug-and-play via a pre-installed USB-A connector. Compatible with Windows, macOS, and Linux, it allows configurable logging and real-time digital output. Researchers, growers, and technicians can access and log PAR data effortlessly for documentation and analysis.
