  • 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.
