Product introduction
Can measure the Chlorophyll content of plants immediately. LCD show the results. Chlorophyll content and leaf nitrogen content has a very close relationship .The meter is conductive to impose reasonable nitrogen and improve the utilization of nitrogen. So this purpose can be to protect the environment, especially water resources, rather than using too much nitrogen fertilizers.

Chlorophyll is the green pigment found in all green plants and is essential for photosynthesis.
Efficient use of nitrogen ( N) fertilizer is important to economical agriculture production and to the quality of ground and surface waters. The chlorophyll meter is a good way to testing for N.
