The atLEAF CHL PLUS is a powerful, handheld, easy to use device for noninvasively measuring the relative chlorophyll content of green leaf plants. Chlorophyll content can be an indicator of the plant's condition.
Plant relative chlorophyll concentration is measured by inserting a leaf into the device aperture. Green leaves of up to 0.1 inch (3 mm) thickness can be measured. It only takes one press of the key to perform a basic measurement.
