Plant canopy measurement instrument

Working principle of Xinwei Huicheng PAR-2000 plant canopy analyzer

Product Introduction:

Photosynthetically active radiation (PAR) is an important indicator for evaluating plant health status and describing plant canopy structure. PAR represents how much light energy can be utilized by plant photosynthesis; The leaf area index can be used to estimate canopy density and biomass, and is an important characterization parameter of plant canopy structure. It is also commonly used to measure the growth of crops and forests. Plant canopy measurement instruments are widely used in research fields such as agriculture, forestry, and botany.

Working Principle:

Plant canopy measurement instrumentThe probe includes 25 PAR light quantum sensors with a spacing of 1cm (sensor center distance), used to measure changes in PAR in ambient light. It is equipped with an external photosynthetically active radiation sensor, which can measure the ratio of PAR above and below the canopy.

Instrument features:

1. Real time measurement of PAR.

2. Simple and intuitive six key control.

3. Automatic recording mode function.

4. Large data storage space.

5. Low power consumption, 4 No. 5 alkaline batteries.

6. External PAR sensors can be used for probe calibration and real-time measurement of PAR values above and below the canopy.
