New Chlorophyll Meter
Apogee Instruments announces a major advance in the non-destructive measurement of leaf chlorophyll concentration. Based on research from scientists at Utah State University represented in the graphs below, Apogee has developed a new optical meter that combines the features of the CCM-200 plus from Opti-sciences with the ability to output a measurement of chlorophyll in units of µmol of chlorophyll per m2 of leaf surface. This patent pending meter is a significant improvement over older meters, which are limited to outputting indexes (CCI or SPAD) that are non-linearly related to leaf chlorophyll.

New Additional Output Unit - Chlorophyll Concentration
- Displays units of chlorophyll concentration: µmol per m2 of leaf surface
- Comparable meters only output relative indices that are non-linearly related to chlorphyll concentration (e.g. CCI or SPAD). For information on how to convert your old index data please contact Technical Support.
- The graphs below (click to enlarge) show how the CCI and SPAD indices relate to chlorophyll concentration,
- Rapid measurement of cholorophyll concentration
- Large 9 mm diameter (63.6 mm2) sampling chamber to integrate a larger leaf area and provide a more reproducible measurement
- Included Field of View Reducer accessory - 19.6 mm2 sample chamber, see details here.
State of the Art Optical Field Measurement
- Measures chlorophyll concentration from leaves without damaging plant material
- Lightweight design facilitates hand-held measurements in the field
- Larger sampling area integrates a larger portion of leaf
- Stores over 100,000 data points, more than most meters
- Integrates with third-party GPS to mark location
- Meter calculates average of user-defined sample sizes to evaluate overall plant health
