AtLeaf 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.
How it works?
Plant relative chlorophyll concentration is measured by inserting a leaf into the device aperture. Green leaves of up to 0.1 inch (3mm) thickness can be measured. It only takes one press of the key to perform a basic measurement.
By utilizing the atLEAF+ four keys you can:
assign species names to the measurements; until 500 names can be stored in atLEAF+
view up to 5,000 measurements stored in the device’s memory
delete the most recently performed measurement
delete all measurements
transfer plant names to the device or measurements to a computer using the USB mode
