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 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.
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 new MEDICAL grade strict tolerance LED source insures repeatability and consistent meter to meter readings.
The CCM-200 plus has the largest on-board memory of any chlorophyll meter, storing over 94,000 measurements internally. 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 into the field. Data transfer is quick and easy through its universal USB 1.1 interface.
