Overview: 

Light Meters

Quality light meters are an essential tool in accurately determining if your crop is receiving the maximum light needed for healthy growth. A light meter allows growers an accurate means of adapting to their plants' needs as the light conditions change during a full growing season.

  • 15 amp rated

Quantam PAR Meter

  • Measures PAR (Photosynthetically Active Radiation) flux in wavelengths ranging from the 400 to 700 nm
  • Fully portable handheld light meter
  • Measures up to 10,000 in units of micro-mol per meter squared per second (umol/m2/s) which is also called Photosynthetic Photon Flux Density (PPFD)
  • Tethers to computers via USB cable for easy data logging
  • Proprietary Quantum Sensor
  • Ultra-low power consumption with built-in low battery indicator
  • Proprietary data logging software
  • Response curve is almost constant (versus Gaussian for digital meters) which yields a much higher accuracy independent of wavelength being measured- great for measuring LED light correctly
