FS-S02 Digital plant chlorophyll meter

Brief introduction:

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