Quantum PAR Meter

Made by Hydrrofarm

Measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from the 400 to 700 nm
Fully portable handheld PAR meter with our highly accurate, integrated Quantum Sensor
Measures up to 10,000 µmol compared with 2,000 µmol 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.
