Description:

The chlorophyll tester can measure the relative content of chlorophyll (in SPAD)

or greenness of plants,nitrogen content, leaf surface humidity, leaf surface

temperature, so as to understand the real nitro demand of plants, and help you

understand the degree of nitro-deficiency in the soil or Whether too much nitrogen

fertilizer is applied, you can increase the utilization rate of nitrogen fertilizer through

the chlorophyll and nitrogen content of this instrument and protect the environment.
