Chlorophyll Concentration
Apogee Instruments, Inc. (Apogee)
Linear OutputThe Apogee chlorophyll concentration meter is calibrated to measure chlorophyll concentration in leaves with units of mol of chlorophyll per m2. This eliminates the problems with relative indexes of chlorophyll concentration.For reference and comparison purposes, the Apogee meter also outputs relative units [CCI or SPAD] if desired.For details see: Parry, C., Blonquist Jr., J.M., & Bugbee, B. 2014.
