GRAIN MOISTURE METER The FieldScout CM 1000 NDVI Meter uses “ point-and-shoot” technology to instantly measure reflected light in the red ( 660nm) and near infrared ( 840nm) spectral bands. The NDVI Meter uses red and near infrared reflectances to calculate NDVI. At 12in( 30cm) , it integrates a 1.5in( 4cm) diameter area on a plant leaf or, at 4ft( 1.2m) , a 4.5in( 11cm) diameter spot on a plant. Laser guides on the NDVI Meter outline the edges of the measured sample area. An ambient light sensor automatically corrects NDVI measurements for varying light conditions. The handheld NDVI meter calculates and displays a running average for multiple NDVI readings. Get greater utility with the built-in data logger for detailed analysis on your PC* . Data logger can function with or without a GPS receiver* * . Durable and highly portable. Includes software.
