The Standard in

Plant Stress Measurement



Chlorophyll Content Meter - works on small & difficult samples & provides a larger reliable measuring range than other instruments

The CCM-300 uses a proven fluorescence ratio technique for chlorophyll content measurement at an affordable price. Readout is directly in chlorophyll content mg/m2, and measurement ratio.


  • Reliable results on very small leaves, stems, petioles, and immature plants
  • Chlorophyll content can now be measured from germination through maturity on most plants
  • High degree of correlation with chemical tests, even at higher chlorophyll content levels.
  • Larger measuring range - reliable measurement from 41 mg/m2 to 675 mg/m2
  • Great for nitrogen management applications because it does a better job with well fertilized plants, used as a reference, in management applications.
  • Allows on-board averaging of up to 30 measurements for nitrogen management applications
  • Integrated GPS/GLONASS location receiver
  • USB port for easy data transfer

Allows measurement of

  • Conifer needles
  • Immature wheat
  • Immature rice
  • Turf grass
  • Aradibopsis
  • Algae on rocks
  • Lichens
  • Seeds
  • Fruit & vegetables
  • Stems and petioles
  • Small leaf grains
  • Moss
  • CCM-300  Chlorophyll Content Meter is designed to measure difficult samples. It can be used on conifers, turf grasses, moss, lichen, immature wheat, immature Arabidosis, stems, and petioles, as well as easier samples, like corn and broadleaf plants. The instrument was designed around research done by Gittelson, Bushman, & Lichtenthaler in 1999. The research shows that this method offers a larger reliable measuring range than absorption style meters, provides a ratio that correlates with chemical tests & provides direct readout of chlorophyll content in mg/m2, that is reliable for many plant species. Adjustments to the direct chlorophyll content readout equation are possible for other species.
