contact information of Yizheng imported wastewater detection instrument test principle

common test principles of exhaust gas analyzer mainly include:

non dispersive infrared analysis principle (NDIR), electrochemical principle, in addition to hydrogen flame ionization method (FID), chemiluminescence method (CLD), magnetic gas pressure method, etc. According to different principles, there are detectors with different structures (usually called sensors of instruments), which are respectively suitable for testing different types of gas components.

the function is to inhale exhaust gas from the exhaust pipe of the car.

therefore, the hydrogen flame ionization method is used to analyze HC, the non light separation principle is used to analyze Co, CO2, the magnetic pressure method or oxidation error method is used to analyze the oxygen emitted by the engine, and the chemical luminescence method is used to analyze no/nox. These methods are widely recommended as the standard methods for engine exhaust analysis by authoritative institutions in various countries. However, due to their complex structure, high supporting costs (millions to tens of millions) and inconvenient operation, they are currently only used for engine or vehicle/motorcycle exhaust analysis. As you often mentioned now, the instruments used in the Euro I, Euro II, Euro III and Euro IV () emission standards of automobiles are such instruments. They are also the necessary form certification and production consistency inspection and testing equipment required by the national development and Reform Commission for automobile/motorcycle manufacturers, which shows the determination to control automobile pollution in the future

the instrument of non dispersive infrared absorption method has the advantages of simple structure, long service life, high measurement accuracy, fast reaction speed, low operation cost and simple operation. It can be used to analyze and test CO (carbon monoxide), CO2 (carbon dioxide), HC (hydrocarbons). Through ADDA, a DDS, a ddc3 address decoding, it can select which route, no (nitrogen oxide) and other gas concentrations, so it is widely used in the analysis of vehicle emission pollutant concentrations

two parallel tubular chambers (one gas chamber is a standard gas chamber, which is filled with N2 gas that does not absorb infrared ray, and the other is a sample gas chamber,

at present, the instruments used in the fields of automobile/motorcycle production line detection, automobile maintenance detection, in-service automobile pollution detection, automobile pollution detection and treatment in China are mainly small instruments based on the principle of non light separation and electrochemical principle, with low cost. Hydrogen flame ionization method and chemiluminescence are also used abroad Method and other large instruments, but the cost is expensive. At present, the former is required by the national motor vehicle pollution detection specifications and standards, but the requirements will be gradually improved in the future. That is, specific gas molecules (including atoms that can provide the required impact and modulus properties and excellent chemical resistance) have specific wavelengths, can absorb infrared rays, and their absorption amount is proportional to the concentration of the gas under constant conditions

the sampling device consists of sampling probe, filter Catheter (made of special materials,

therefore, the hydrogen flame ionization method is used to analyze HC, the non spectroscopic principle is used to analyze Co, CO2, the magnetic pressure method or oxidation error method is used to analyze the oxygen emitted by the engine, and the chemiluminescence method is used to analyze no/nox. These methods are widely recommended as the standard methods for engine exhaust analysis by national authorities. However, due to their complex structure, high supporting costs (millions to tens of millions), and the operation is not simple enough, At present, it is only used for engine or vehicle/motorcycle exhaust analysis. As you often mentioned now, the instruments used in the Euro I, Euro II, Euro III and Euro IV () emission standards of automobiles are such instruments. They are also the necessary form certification and production consistency inspection and testing equipment required by the national development and Reform Commission for automobile/motorcycle manufacturers, which shows the determination to control automobile pollution in the future. Therefore, the detector outputs electrical signals, which are displayed by the LCD display part (such as the LCD) after data processing or output for subsequent processing.

requires that the pipe wall does not adsorb gas, does not react with the measured gas to ensure measurement accuracy), consists of water separator and air pump,

the detector of the instrument (commonly known as the optical platform) is the heart of the instrument, and the infrared light radiated by the internal light source is modulated into a beam of a certain frequency, This light beam passes through the sampling (detection chamber) air chamber, and then passes through the filter and enters the detector. After receiving these optical signals, the sample detector converts them into electrical signals for output, and the system processes the data to obtain the corresponding concentration of the measured gas from a good rigidity
