FieldScout CM 1000 NDVI Meter

“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 over 3,000 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)**
•  Includes hard carrying case and batteries

    *GPS interface requires two cables.  The GPS/DGPS cable (item 2950CV5) is available from Spectrum.
      A PC serial interface cable supplied by the manufacturer of the GPS receiver is also required.
  **PC cable connects to a computer USB port.

Measurement Sample: Plant leaves, turf grass canopy
Measurement System: Reflectance of 660 nm and 840 nm light
Measurement Area: Conical viewing area between 12 and 72 in
Minimum Distance: 12 in (30.5 cm) from lens
Maximum Distance: Accuracy is unknown beyond 72 in from lens
    Distance From Lens:    Sample Area (Diameter):    
    12 in (30.5 cm)    0.53 in (1.35 cm)

Receptor: (4) photodiodes: (2) for ambient light and (2) for reflected
light from the sample (leaf, turf)
Measurement Units: NDVI (Normalized Difference Vegetation Index on
                   a scale of -1 to 1
