An oxygen-containing instrument for measuring the flue gas is referred to as a portable flue gas analyzer. The commonly used portable flue gas analyzers are primarily thermal magnetic and zirconium oxide. (1) Thermal magnetic oxygen analyzer of the portable flue gas analyzer is based on the physical properties of particularly high magnetic rates of oxygen in the flue gas composition to determine oxygen content in the flue gas. Oxygen is a magnetic gas (which can be referred to as a magnetic gas from magnetic sites) and is drawn into the magnetic field in an uneven manner, leading to a stronger magnetic field. The presence of heaters at the site reduces magnetic field pull and discharges from the magnetic field, driven by unheated oxygen molecules with high back magnetic rates, resulting in a heat-magnetic convection or magnetic wind phenomenon. After measuring the size of the magnetic wind, at the required pressure, temperature and flow of the air sample.

The portable flue gas analyzer, which uses heat-heated flame organization detectors (HFID) to measure total hydrocarbons (including THC, VOC, TOC, NMHC), is a standard measurement technique that fully complies with the regulations. Portable flue gas analyzers have a wide range of applications, ranging from smoke boilers to combustion stoves to high-concentration solvent users. The outstanding relevance of lipids, alcohols, esters, ketone and aromatic compounds provides a solid method for detecting total hydrocarbon concentrations. It is based on the use of hydrogen and air burning flames, when organic compounds enter flames burned with hydrogen and oxygen, when chemical ionizing occurs at high temperatures and when ionizing occurs several orders of ion above the base current. The directional effect of the high-voltage field is to form an ion flow, with a weak ion flow passing through high resistance.

In recent years, as the economic level of the country has risen year by year, and as people progress in their daily lives, the environment has been excessively polluted and the water has blackened and odoured. This not only destroys people ' s daily environment, but also endangers their health, and the State attaches great importance to environmental protection. In order to save the living environment on which people depend and to deal with water pollution, and in response to calls for national environmental protection, water quality monitoring has become a very necessary process in the context of the water environment, for which water quality detection instruments provide strong guarantees. Water quality detection instruments have played a leading role in the rise of future malls and demand for future malls has grown rapidly. As the epidemic has affected us, and as all the negative aspects of our lives have emerged, we should step up our efforts to uphold hygiene and sanitation, especially water quality and environmental pollution.

In recent times, many clients have called to consult the source-friendly water-quality detection equipment, asking about the price and how to select suitable water-quality-testing equipment for themselves, even though the first purchase of a water-quality-testing device is still a demand for an additional specialized detection device, and we need to take into account the following important factors before buying it. 1. We all know that there are many types of water quality detection instruments, such as COD, ammonia nitrogen, total phosphorus, chlorine ion-specific tests, heavy metal tests, parameter tests, etc., that there are many differences between different water quality parameter detection instruments, and different detection devices, and different sizes for some parameters, so we can think about the specific items being tested, or what data are needed for ongoing tests.

The multi-purpose flue gas analyzer is an instrument for analysing the flue content and is widely used. The flue gas analysis equipment is primarily used in such occupations as fertilizers, metallurgy, petrochemicals, cement production and power generation. The advantages of multifunctional flue gas analyzers are particularly evident and are reflected in the following: Multiple gas coefficients can be analysed, with differential pressure and flow speed options. 2. Sampling is well developed. Actively turn on the creeping pump, discharge condensation water, very suitable for wet gas monitoring and analysis. At the same time, the instrument is equipped with a three-tier filter and a particle collection device, which can be used to filter dust and smoke particles. 3. Wireless manipulation. (b) Operator remote manipulation of operating devices; Prevention of on-site contamination by operators. 4. The pull is weak. The internal high power thin membrane pumps with a maximum vacuum of up to -60 kPa and a pneumatic pneumatic pressure of 20kPa are functional. Five.

How can the in situ accuracy of a smoke analyzer be fully verified? The following recommendations are made in this paper: 1. Operation Flow Consistency Validation 1.1 Tests own flow and full flow Consistency 1) Tests external flow meters, pumps, and flow count readings are recorded. 2) Tests are connected to sample guns, catheters, preprocessors, filters ..., pump, and flow readings are recorded. 3) The difference between two readings does not exceed 5 per cent.1.2 Operational flow consistency of high-pressure sampling holes 1) 2) The same series of flow meters measure the flow during high-negative sampling hole operations (noticing that it must be external flow meters rather than light-trusting the flow measured by the instrument itself). 3) The difference between two readings does not exceed 5% 1.3 Smoke
