CCM-200 Plus Chlorophyll Content Meter
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 400 research citations. Designed as an affordable solution, the CCM-200 plus provides an included, programmable, measurement averaging option. Averaging between 2 to 30 samples are possible for nitrogen management. It includes a non-volatile flash memory that can store between 94,000 and 160,000 measurements. Data transfer is by USB port to Excel ® or other comma delineated spread sheets.
features
- Fast - non-destructive measurement at an affordable price
- Cited by more than 400 published scientific papers
- User selected sample averaging size from 2-30 measurements for nitrogen management applications
- Comma delineated files may be opened directly in Excel ® using a USB port
- An almost unlimited memory included for data logging
- Lightweight, Hand-Held Design Optimized for Field Work
- Displays Chlorophyll Content Index or CCI
CCM-300 Plus Chlorophyll Content Meter
features
- Reliable results on very small leaves, stems, petioles, and immature plants
- Chlorophyll content can now be measured from germination through maturity on most plants
- High degree of correlation with chemical tests, even at higher chlorophyll content levels.
- Larger measuring range - reliable measurement from 41mg/m2 to 675 mg/m2
- Great for nitrogen management applications because it does a better job with well fertilized plants, used as a reference, in management applications.
- Allows onboard averaging of up to 30 measurements for nitrogen management applications
- USB port - data files open directly into Excel ®
- 2 Gigbytes of memory
quick and easy-to-use
The following video demonstrates that the CCM-200 or CCM-300 chlorophyll meters are quick and simple to use. Within 30 seconds, the meter is turned on, calibrated and ready for measuring. The video demonstrates the following steps:
- Turn on instrument
- Run a measurement
- Start calibration and hold down sensor head
- Overwrite old data file and start a new file
- Place sensor head on leaf and hold down
- A measurement result is displayed on the screen
