Detects Stress Earlier Than Visual Monitoring-Before Plant Growth Is Affected
Based on an exclusive patent license from NASA, the Spectrum Chlorophyll Meter
uses point and shoot technology to instantly tell you relative chlorophyll content,
a key early indicator of plant health.
Integrates a large 0.5" diameter area at 12" on a plant leaf or a
4.5" diameter spot on turf grass at 4 feet. High powered lasers outline
the edges of the measured sample area of leaf or canopy.
Ambient light sensor automatically corrects for varying light conditions. The
handheld Spectrum 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. *** Try before you buy! *** Call for
