Description

The atLEAF STD chlorophyll meter is a handheld, easy to use device for non-invasively measuring the relative chlorophyll content of green leaf plants. Chlorophyll can be an indication of the plants condition and uptake of nutrients. The chlorophyll content is simply measured by placing the leaf into the aperture of the device. Green leaves of up to 0.1 (3mm) thick can be measured.

There are three models.  The atLEAF STD chlorophyll meter  is the basic model without USB or Bluetooth.    The atLEAF PLUS has a USB connection but no Bluetooth connection. The atLEAF BLUE chlorophyll meter  is the top of the range model with USB connection and Bluetooth.   see www.atleaf.com

By utilizing the four atLEAF  STD chlorophyll meter keys you can

  • View up to 64 measurements stored in the device’s memory
  • Delete the most recently performed measurement
  • Delete all measurements
  • Calibrate the instrument

How does it work?

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 four atLEAF CHL STD keys you can:

  • view up to 64 measurements stored in the device’s memory
  • delete the most recently performed measurement
  • delete all measurements
  • perform instrument calibration
