Spring is an important period for large-scale seed production in agriculture, and it is also a crucial period for spring production. Therefore, in order to ensure the safety of seed use, it is necessary to conduct quality inspection on the seeds sold on the market. The contents of the inspection include the determination of seed purity in addition to routine tests such as seed moisture and germination rates. In order to shorten the testing period, relevant departments need to use a specialized seed DNA extraction instrument to break the seeds and extract the seed DNA for further detection and analysis.
With the development of agricultural breeding technology, the number of seed species is increasing, and the genetic basis between seed varieties has become narrow. Many seed varieties are very similar, and it is difficult to distinguish them from the appearance. Therefore, the quality of the seeds needs to be tested from the inside. Seed DNA. However, before this test is carried out, the first thing to do is to grind the seed, which requires rapid and efficient extraction of the seed DNA. The past methods needed to be extracted in the presence of liquid nitrogen for several hours. Now, with the help of a seed DNA extractor, the work can be completed in a very short time, which greatly improves the efficiency of seed DNA detection. Applying it to spring seed quality inspections and other work can effectively ensure that the relevant work is completed on time and in accordance with the quality, ensuring the safety of the farmers' friends.
The application of seed DNA extractor in the quality inspection of spring seeds not only has an obvious effect on improving the effectiveness of the work, but also helps the regulatory authorities to increase the frequency of detection of the planting market, and maintains a high-pressure supervision on the seed market. To combat the problem of counterfeiting and counterfeiting in seed production, and further standardize the seed and seed marketing market order, it not only safeguards the legitimate rights and interests of farmers and seed production enterprises, but also effectively purifies the seed market, creating the basic conditions for the rapid development of modern agriculture.
Low-temperature 1-color Pyrometer
This classification includes one color infrared pyrometers measuring range is 250℃-2200℃. The one color pyrometers currently on market are mostly narrow-band pyrometers. Its principle of temperature measurement is to determine the temperature by detecting the radiant energy that occurs in a narrow wavelength range of an object. The temperature a pyrometer measured is the average temperature in an area, and the measuring result is affected by emissivity, lens contamination and background radiation.
To use 1-color pyrometer mode, the measured area of the object should be large (it can fully fill the target field of view) , object surface should be relatively flat (not curved), measurement direction should less than 30 degrees, and the physical and chemical state of the measured object surface should be stable (not in the process of oxidation, gasification or liquefaction) , the optical channel should with less dust and without blocking and attenuation.
Main applications include: inductioin heating,heat treatment,Galvanized wire ,also suitable for temperature measurement in a good environment. Products in this catalog are usually applied to metallurgical industry(rod and wire mills.Hot rolling mills), foundry, cement kiln, induction heating, heat treatment, heating furnace, vacuum furnace, monocrystalline silicon, polysilicon, semiconductor and other industrial temperature measurement.1-color pyrometer, monochromatic infrared pyrometer, one color pyrometer, one-color infrared pyrometer
