Apogee Instruments SQ-520 - sonda pro měření PAR/PPFD

Real-time PAR/PPFD measurement for LED lighting

The Apogee Instruments SQ-520 is a PAR/PPFD sensor with USB output designed for precise measurement of photosynthetically active radiation, especially under LED lighting. It connects directly to a computer via a USB cable for real-time spot, graphical, and logging measurements of PPFD, using the included software. The sensor also functions as a standalone logger by connecting to a standard 5V DC USB power adapter. Its internal memory stores up to 10,000 user-specified periodic measurements in CSV format.

This sensor is crucial for growers using LED lighting, as it measures PAR and PPFD, which are vital for plant growth, unlike traditional LUX meters. With a spectral response range of 389-692 nm ± 5 nm and a resolution of 0.1 µmol × m⁻² × s⁻¹, it provides detailed data. The sensor is fully dust and water-resistant (IP68) and can be submerged up to 30 meters, making it suitable for diverse cultivation environments, from indoor grow tents to commercial facilities.
