In the field of detection, with the development of science and technology, many classic detection methods have been instrumented in the past, that is, the use of professional equipment to replace the cumbersome manual operations in the past, and the principle used is based on the previous classical detection methods. The most representative detection instrument is the Kjeldahl nitrogen determination instrument. Its detection principle is the classical Kyiv method for determining nitrogen. Therefore, as the Kjeldahl constant instrument product is constantly updated and upgraded, the function is continuously improved, and the degree of automation is continuously improved. However, the Kjeldahl method through it is unchanged, and in the analysis process Kjeldahl is also widely used as an analytical method. Lead-acid Electric Tricycle to the largest number of lead-acid batteries. Lead-acid batteries, the lowest price, but also the most commonly used. Its less contaminated ingredients, good recyclability. The internal battery to wear wall welding connection, high current discharge performance. Battery cover with PP material, shell cover heat seal, to avoid leakage of the battery when used. Grid alloy with multiple corrosion-resistant alloy, the grid is pressure casting, grid corrosion to solve the short circuit Lead Acid Electric Tricycle,Lead-Acid Battery Electric Tricycle,Color Custom Electric Tricycle,Lead Acid Battery Electric Tricycle QuZhou Benneng Vehicle Co.,LTD , https://www.cn-ebikes.com
Many people do not understand why Kjeldahl instruments are becoming more and more advanced, but the means to determine the end point is still the use of color methods, this is the past to start the determination of nitrogen is often done by manual acid-base titration final Analytical work, and then through the naked eye to observe the color change of the solution to determine the end point, although the naked eye there is a certain error, but this method is indeed very effective and reasonable, so after the Kjeldahl generator, still using this classical analysis method, On the other hand, because with the advancement and development of sensor technology, the color measurement can no longer be observed with the naked eye, but by using a color sensor, which further reduces the error of manual observation and improves the Kjeldahl nitrogen content. The instrument's detection accuracy, so Kjeldahl is still using the color method as an analysis method, there is no big problem.
There are many types of Kjeldahl nitrogen analyzers currently on the market. In general, the measurement range, measurement accuracy, and titration accuracy are basically the same. However, due to the different production materials and production processes adopted by different manufacturers, the technical level of the products is different. There will be a large gap between quality and other factors. Therefore, when selecting, we should try our best to cooperate with top-ranking companies such as top-level Yunnong who have relatively good R&D, production, and after-sales services. This will not only ensure product quality, but also in use. Any problem can also be solved technically, eliminating worries.
4, the use of advanced plate curing, into technology, improve the binding of active substances and grid, extend battery life
5, the positive plate for the battery tube, negative plate is paste type, with long life, deep charge and discharge performance and other significant advantages
6, the use of polyester fiber pipe and PVC separator can effectively solve the use of pipe rupture and lead to short circuit caused by dendrite, to extend battery life
