provides accurate chlorophyll readings on intact leaf samples. No grinding, no time consuming assays, just non-destructive chlorophyll measurements for on-sight, point of contact analysis
CCM-200 Non-destructive Chlorophyll Content Measurements
The New CCM-200 Chlorophyll Content Meter provides fast accurate, chlorophyll readings on the intact leaves of plants and crops.
No more grinding or destructive assays!
The measurement is rapid, accurate and simple to obtain, allowing researchers and agronomists to gather and evaluate mission critical data faster than ever before.
Especially useful for improving and Fertilizer management programs, the CCM-200 is also ideal for , Leaf Senescence Health Determination and studies. Furthermore, the affordability and ease of use make it an exceptional teaching tool for botany and plant science courses. Perhaps the best feature of the CCM-200 is the ample on-board memory. Storing over 4, 000 measurements internally, users can record a whole day' s work without ever having to return to the lab or worrying about limited memory. This feature plus the hand-held, battery operated design makes the CCM-200 the most field efficient chlorophyll content meter on the market.
The CCM-200 means you no longer have to deal with external data loggers and add-ons. All you need for precise chlorophyll measurements is in one lightweight, compact, affordable package. Technology has moved on and now, so can you. The CCM-200 is an instrument that no plant scientist can do without.
Changes in chlorophyll content can occur as a result of nutrient deficiencies, exposure to environmental stress, exposure to certain herbicides, and differences in light environment during growth ( shading) . Chlorophyll content can be used to manage nutrient optimization programs that both improve crop yield and help protect the environment. Testing for herbicide damage can indicate the need for a change in herbicide selection or application methods; in order to maintain good weed control while having minimum impact on crophealth.
Laboratory methods for determination of chlorophyll content are both time consuming and destructive to the sample. Typically a sample must be detached, ground up in a solvent, then assayed in a spectrophotometer. A sample can be measured only once precluding the monitoring of trends in chlorophyll content over the growing cycle. The CCM-200 provides non-destructive, rapid measurements of relative chlorophyll content without the need to detach and grind a sample.
Chlorophyll has several distinct optical absorbance characteristics that the CCM-200 exploits to measure relative chlorophyll concentration without destructive sampling. Strong absorbance bands are present in the blue and red but not in the green or infrared bands, hence the green appearance of a leaf. By measuring the amount of energy absorbed in the red band an estimate of the amount of chlorophyll present in the tissue is possible. Measurements in the infrared band show absorbances due to cellular structure materials. By using this infrared band to quantify bulk leaf absorbance, factors such as leaf thickness can be taken into account in the CCI ( Chlorophyll Content Index) value.
