Plant Chlorophyll Content Meter

A handheld plant stress detector measures the amount of chlorophyll in foliage, based upon light reflected from the plant. It collects light reflected from a target plant, separates it into two different wavelength bands (red and infrared), and analyzes the reflected light to determine plant physiological stress. It is used to learn how leaf chlorophyll content is affected by nutrients, biological influences, herbicides, and other environmental impacts.
