QUANTUM PAR METER Fully portable handheld PAR meter features our highly accurate, integrated Quantum Sensor that measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700 nm. It measures up to 10,000 ?mol compared with 2,000 ?mol for other meters on the market. • Data logging capability using standard mini-USB cable and proprietary data logging software available at hydrofarm.com • Low power consumption with built-in low battery power indication • Constant linear response curve (as opposed to other meters’ Gaussian response) yields higher accuracy independent of wavelength—perfect for measuring LED light output • Automatic sun or electric light calibration modes ensure accurate readings no matter the source
