• Chlorophyll Meter

Chlorophyll Meter


“Point-and-shoot” technology to instantly measure relative chlorophyll content


  • Detects stress earlier than visual monitoring
  • Technology based on an exclusive patent license from NASA
  • 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 (not included)**
  • Compatible with SpecMaps™ online web-mapping application
  • 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; Ambient and reflected 700 nm and 840 nm light are used to calculate the relative chlorophyll index
Measurement Area Conical viewing area between 12 and 72 inches
Minimum Distance 12 inches (30.5 cm) from lens
Maximum Distance Accuracy is unknown beyond 72 inches from lens
