NEW Upgrade Quantum PAR Meter - High precision, Grow light meter, Indoor plants meter. Product Description Quantum PAR meter is fully portable handheld PAR meter features our highly accurate, integrated Quantum Sensor that measures PAR (photo synthetically active radiation) flux in wavelengths ranging from the 400 to 700 nm. It measuresup to 10, 000 MOL compared with 2, 000 moll for other meters on the market. Constant linear response curve (as opposed to other meters quo; 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.
