Description

The atLEAF PLUS  chlorophyll meter is a powerful, 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 PLUS chlorophyll meter 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.  The atLEAF STD is the basic model without USB or Bluetooth.   see www.atleaf.com.

By utilizing the four atLEAF PLUS chlorophyll meter keys you can

  • Assign species names to the measurements; device can store up to 490 names
  • View up to 9 554 measurements stored in the device’s memory
  • Delete all measurements
  • Transfer plant names to the device or measurements to a computer using the USB mode
  • Display sensor temperature in degrees F and C
  • Display time
  • Perform and show average on selectable number of stored measurements
  • Modify multiplication factor and offset for measures allowing e.g. device to output the measures in SPAD units
  • Each performed measure has associated device and sensor temperature

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 four atLEAF CHL PLUS keys you can:

  • assign species names to the measurements; device can store up to 490 names
  • view up to 9,554 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
  • display sensor temperature in °F and °C
  • display time (*)
  • perform and show average on selectable number of stored measurements

Each performed measure has associated device time and sensor temperature (*).

(*) atLEAFSoft PRO software is required to sync the device time with PC time and to transfer the measurement temperature to PC
