The size and dynamic change of leaf area index have a direct relationship with the growth and development of plants. Detecting the leaf area of ​​plants can detect the growth of plants, monitor the growth status of plants, and thus evaluate the corresponding ecological environment, so plant leaves are Area measurement is very important. It is also an important parameter for studying plant growth patterns, population photosynthetic and formulating plant cultivation measures and technical standards. Therefore, the leaf area meter is well worth promoting.
The rare-earth metal thick film heating technology is one of today's most innovation and forward-looking solution for electric heating field.The thick film heating tubes/elements are produced by screen-printing dielectrics (5 layers), resistance (palladium-silver), conductor (silver) and isolation glazes on the substrate and sintered 7-9 times at temperature over 900℃.
With 2200W Thick Film Heating Tube simple tubular structure, it can heat water flow inside the tube. Electric Circuit printed on tube surface, to heat the water flow inside. For applications where space is limited, this simple profile heater offers high thermal power density and fast response times to heat up or cool down (due to low thermal mass)

In the past, people's leaf area measurement was mainly measured by hand. Such a detection method has high manpower and material costs and is usually destructive to vegetation, and is not suitable for large-scale measurement of vegetation growth changes. After design and research and development, the appearance of leaf area meter not only can carry out nondestructive testing of leaf area, but also the instrument is lightweight and portable, and it is also very convenient to work in the field. The detection can accurately and quickly determine the leaf area and related parameters of the blade, which is more accurate and convenient than the manual measurement beforehand. It can also measure the area of ​​the harvested plant leaves and other sheet objects, and its scope of use is also very good. Extensive, not only used in the determination of leaf area, there are other aspects. When manually detecting the leaf area, many people need to help record data, which takes a long time and high labor costs. Now with the leaf area meter, one can measure larger leaf area at one time, and can also determine various parameters of the leaf: leaf area, average leaf area, leaf width, leaf length, so that the detected data is more representative. Moreover, the leaf area meter can save the data by itself, which can reduce the error-prone step of data recording. People can also perform data detection based on evidence. These are the reasons why it is worth promoting!
