Zhu J., Tremblay N., Liang: "the atLEAF Chl meter can be used as an inexpensive alternative to the SPAD-502 meter"
M.Lundy, S.Wright, S.Orloff, R.Hutmacher : "The AtLeaf meter successfully distinguished between wheat growing under different N and water conditions.
atLEAF CHL PLUS is a powerful, handheld, easy to use device with USB connection 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 1/7 inch (3mm) thickness can be measured. It only takes one press of the key to perform a basic measurement. Each device is factory calibrated: accuracy +/-0.5. Free atLEAFSoft software for PC Windows available for download.
