Detects stress earlier than visual monitoring for healthier plant growth. Based on an exclusive patent license from NASA, the FieldScout CM 1000 Chlorophyll Meter uses “point-and-shoot” technology to instantly tell you relative chlorophyll content. At 12in(30cm), it integrates a large 1.5in(4cm) diameter area on a plant leaf or, at 4ft(1.2m), a 4.5in(11cm) diameter spot on turf grass. Laser guides outline the edges of the measured sample area of leaf or canopy. An ambient light sensor automatically corrects measurements for varying light conditions. The handheld meter calculates and displays a running average for multiple readings while simultaneously recording each sample in the built-in data logger for detailed analysis later at your PC*. Data logger can function with or without a connection to a GPS receiver**. Durable and highly portable, the FieldScout Chlorophyll Meter is an essential tool for more effectively managing your nitrogen program. Use the powerful SpecMaps online application to discover the value of spatially variable sensor measurements. Mapping program requires GPS; not included.

* Spectrum’s PC cables connect to a 9-pin serial port. USB-Serial adapter (item 3661USB) required for connection to computers with only USB ports. ** 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. *** 1.5" (3.8 cm) rods may require a TDR 300 firmware update. Please contact us for instructions.
