Hydrofarm Quantum PAR Meter

This portable handheld meter is equipped with an integrated quantum sensor that measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from 400 to 700 nm. The meter measures up to 10,000 µmol and stores 99 daily averages and totals that can be downloaded using the included USB cable. The meter’s constant linear response curve produces high accuracy independent of wavelength, making the meter ideal for measuring LED light output. Automatic sun or electric light calibration modes provide accurate readings regardless of the source. Low power consumption ensures outstanding efficiency, and the meter features a built-in battery power indicator. USB data/charging cable and storage/carrying case included. One-year manufacturer’s warranty.
