Chlorophyll Meter Model : LI-CM4

The LI-CM2 Chlorophyll Meter is a specialized device designed for measuring the chlorophyll content in plant leaves. 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 the utilization of nitrogen and protect the environment.

The LI-CM4 Chlorophyll Meter is a portable, hand-held instrument used to assess the chlorophyll concentration in plant leaves, providing valuable information about plant health and nutritional status. It is widely used in agricultural research, crop management, and plant physiology studies.

Key Features

1. Non-destructive Measurement: Allows for rapid and non-destructive measurement of chlorophyll content, enabling continuous monitoring of plant health without damaging the leaves.
2. High Precision and Accuracy: Equipped with advanced optical sensors and calibration technology to ensure precise and accurate readings of chlorophyll levels.
3. Easy to Use: The device features a user-friendly interface with a clear LCD display, making it easy to operate even for those with minimal training.
