Enabling better global research outcomes in soil, plant & environmental monitoring.

MC-100 Chlorophyll Concentration Meter

The MC-100 Chlorophyll Concentration Meter directly measures and displays chlorophyll concentration from intact leaf samples without damaging the plant material. This data can be used to monitor environmental stress, evaluate the demand and efficacy of fertiliser treatments and optimise harvest schedules throughout the growing season.

Teaching and Research Applications

Monitoring environmental stress, evaluating efficacy of fertiliser treatments, optimising harvest schedules, pest control, crop breeding.

Consistent Readings

The MC-100 uses a larger sampling area to integrate a larger leaf area and provide a more reproducible measurement. A field of view reducer can be used if the leaf width is narrower than the 9.0 mm sample chamber.

State of the Art Optics

The new meter, optimised for field work, includes state-of-the-art optics with rapid sampling, a larger display, and sample memory that can be downloaded to a computer.

Measure Chlorophyll in µmol per m2

Chlorophyll is vital for photosynthesis and its concentration indicates plant health and nutrition. Apogee is proud to announce a major advance in the non-destructive measurement of leaf chlorophyll concentration. Based on the research of scientists at Utah State University, represented in the graphs below, Apogee has developed a competitively priced optical meter that outputs a measured estimate of chlorophyll in units of µmol of chlorophyll per m2 of leaf surface. The linear output of this patent pending meter is a significant improvement over older style meters, which output indexes that are non-linearly related to leaf chlorophyll.
