Best Plant Nutrition Management Method
Our chlorophyll meter instantly measures the relative chlorophyll content (in SPAD) or greenness of plants, nitrogen content, foliar moisture, and foliar temperature to understand the true nitro requirements of plants and to know if the soil is deficient in nitro or if too much nitrogen has been applied.
This device can be used to increase the utilization of nitrogen fertilizer and to protect the environment. It can be widely used in agriculture and forestry-related research units and universities for research on plant physiological indicators and agricultural production guidance.
- Low power mode design, built-in large-capacity lithium-ion rechargeable battery, with anti-overcharge function, energy-saving and environmentally friendly, and convenient for outdoor operation.

Product Principle
- Calibrate and calculate the measurement value of the chlorophyll meter. Two LEDs emit light one by one, the received light is converted into an electrical signal and the ratio of light intensity is used for calculation.
- After the intruder has clamped the sample, the two LEDs emit light again, and the light transmitted through the blade hits the receiver, which is converted into an electrical signal, and the intensity ratio of the transmitted light is calculated.
- From the values in steps 1 and 2, the SPAD measurement is calculated, which represents the current relative chlorophyll content of the clamped sample sheets.
