Mesureur de la chlorophylle

Detect stress earlier than visual monitoring for healthier plant growth. Based on an exclusive patent license from NASA, the Field Scout CM-1000 Chlorophyll Meter uses "point-and-shoot" technology to instantly tell you relative chlorophyll content. It integrates a large 1 1/2" diameter area at 12 inches on a plant leaf or a 4.5" diameter spot on turf grass at 4 feet. 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 GPS/DGPS. Requires cable. Durable and highly portable, the Field Scout Chlorophyll Meter is an essential tool for more effectively managing your nitrogen program.
