The patented MC-100 directly measures and displays chlorophyll concentration from intact leaf samples without damaging the plant material. The meter is calibrated to measure chlorophyll concentration with units of µmol of chlorophyll per m2. For reference and comparison purposes the meter also outputs relative units (CCI or SPAD). Typical application include chlorophyll concentration determination in leaves for assessment of nutrient status, fertilizer requirements, evaluation of stress, and optimization of harvest.
