FieldScout CM 1000 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 over 3,000 measurements (1,350 with added GPS/DGPS option)
-
Configure and download meter with FieldScout® software (not 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.
