Fieldscout NDVI

a portable meter for nitrogen management


“Point-and-shoot” technology to instantly measure red (660 nm) and near-infrared (840 nm) spectral bands

  • Detects stress earlier than visual monitoring
  • Computes Normalized Difference Vegetative Index (NDVI)
  • Laser guides outline the edges of the measured sample area
  • Calculates and displays a running average for multiple readings
  • Connects to any GPS receiver that has a serial output option
  • Equipped with internal data logger and RS-232 port
  • Records 3,250 measurements (1,350 with added GPS/DGPS option)
  • Configure and download meter with FieldScout® software and USB-to-3.5mm-Stereo-Plug Adapther (Item 3661U.(included)
  • Compatible with SpecConnect
  • Includes hard carrying case and batteries
