Chlorophyll Content Meter

Proven performance at a great price

The CCM-200 plus Chlorophyll Content Meter is an updated version of the very successful CCM-200 instrument. It is a reliable leaf absorption style meter with over 1,000 research citations. Designed as an affordable solution, the CCM-200 plus provides averaging between 2 to 30 samples for nitrogen management. Non-volatile flash memory stores up to 50,000 measurements.


  • Fast, non-destructive measurement at an affordable price
  • Cited by more than 1,000 published scientific papers
  • User selected sample averaging size from 2-30 measurements for nitrogen management applications
  • Data stored in comma delimited files
  • Integrated GPS/GLONASS location receiver
  • USB port for easy data transfer
  • Lightweight, Hand-Held Design Optimized for Field Work
  • Displays Chlorophyll Content Index (CCI)
  • The CCM-200 plus is designed to be the most repeatable portable chlorophyll content meter available. It incorporates a large measuring area for signal averaging. This approach provides a more reliable reading that takes into account small structure variations that can affect repeatability and reliability when compared to smaller area sampling. Accuracy of measurement is determined by correlation with chemical tests. Results have shown that the CCM-200 is as accurate as any chlorophyll meter on the market. Employing a medical grade strict tolerance LED source insures repeatability and consistent meter to meter readings.

    The CCM-200 plus has large on-board memory, storing 50,000 measurements. Users can record months of measurements as well as input their own comment lines without worrying about limited memory or lugging additional equipment such as data loggers or PCs in the field. Data transfer is quick and easy through USB connection.
