Plant PhotoMeter

The plant photometer measures the light intensity absorbed or reflected by plant leaves through a photoelectric sensor, reflecting chlorophyll content and photosynthetic efficiency. It is used in agricultural research, plant physiological monitoring, and crop nutritional diagnosis to help understand plant growth conditions.
Selection
When selecting a plant photometer, consider whether the measurement wavelength range covers the characteristic bands of chlorophyll, check the instrument's calibration stability, confirm its portability and data storage functions, match the probe size according to the crop type, and refer to the measurement accuracy requirements of the actual application scenarios.
