Portable chlorophyll content meter CM1000



Usage: The CM-1000 chlorophyll meter is used to accurately measure the relative chlorophyll content of plants and crops, which can improve the application of nitrogen fertilizer

To understand the true nitro requirements of plants and to help you understand the level of soil nitro deficiency or whether too much is being applied

Added nitrogen fertilizer. With this instrument, you can increase the utilization rate of nitrogen fertilizer and protect the environment (prevent the application of too much nitrogen)

The environment, especially water, is polluted by fertilizer.
