Portable Chlorophyll Meter

Chlorophyll Meter is able to measure chlorophyll content of plants and leaf temperature. Chlorophyll content and leaf nitrogen content have a very close relationship. Thus, chlorophyll content can reflect plants demand for nitro. Using the instrument can do go to put nitrogen fertilizer reasonably, improve utilization of nitrogen and protect environment.


* Enter the name of the plant, the standard nitrogen content and utilization, the standard fertilizer can be directly calculated.

* Chlorophyll, leaf temperature are displayed on same screen at the same time, and can be stored at the same time.

* USB interface can be connected to the computer to export the measured data, to facilitate the management and analysis of plant nutrients. (Only for CM-B)
