The biggest competitive pressure on domestic manufacturers comes from foreign companies. The internationally renowned gas detector manufacturers have branches in China, Huarui, Insco, Figaro, Mei Sian have a high market position, the main reason for this situation is that the product technology level of domestic companies is much lower than that of international companies, and relatively large domestic enterprises purchase more foreign products. The backwardness of the technical level of domestic production enterprises hinders their own development, reduces their competitiveness with international enterprises, and seriously restricts the development of Chinese enterprises.
3. The product line of domestic enterprises is relatively short
At present, a prominent feature of domestic gas detector manufacturers is that the product line is relatively short compared to foreign companies and the application field is limited. Most of themgas detectorIt is used in industry, some of which are used in household gas alarms, and a few products are used in environmental protection, agricultural indoor gas detection, biogas analysis, biogas safety monitoring, dangerous goods storage and transportation, and other fields. The relatively short product line makes China's gas detector products can not be applied to more fields, many enterprises focus on a certain field, affected by the development of the industry and policies in this field, once a certain industry introduces some policies that are not conducive to the development of the industry and gas detector, it will have a significant impact on the business of enterprises focusing on the industry, and the short product line of enterprises in the industry has played a role in limiting the overall development of the gas detector industry. In the future, China's gas detector manufacturers should gradually expand their production lines while strengthening their own economic strength, and expanding the application field from industry to other fields will be the future development trend.
2. Gas detector market size and application fields
(a)gas detectorIndustry market size
According to the data provided by the National Bureau of Statistics, the total industrial output value of the whole industry in 2012 was 711.2 billion yuan, an increase of 20.16% year-on-year; the industrial sales value was 695.5 billion yuan, a year-on-year increase of 20.21%; the profit was 60 billion yuan, a year-on-year increase of 14%. As an important branch of instrumentation, gas detector (also known as "gas detector") has a wide range of applications, covering industry, agriculture, transportation, science and technology, environmental protection, national defense, aerospace and daily life.
The progress of science and technology isgas detectorThe development of the instrument industry provides conditions, the promotion of market and government policies, the progress of people's safety awareness, and the improvement of relevant regulations and laws are the core driving force for the development of the gas detector industry, which drives the negative gas detector instrument industry in a period of rapid industrial growth. Between 2008 and 2012, the industry grew at an average rate of 23%. It is expected that by 2015, the market size of the entire industry will reach 18.176 million.

According to the use and technical requirements of gas detectors, the market can be divided into civil and industrial gas detector markets; The civil market has relatively low requirements for product performance and low prices; The industrial market has high requirements for product quality and performance, and also pays attention to after-sales service. Compared with the civilian market, the price is much higher, and industrial gas detectors are divided into three categories: portable, fixed, and system. Industrial gas detector products are mainly used in gas, petroleum, chemical, metallurgy, coal and other industries, with a market size of about 7,844.2 million yuan.
(2) The current status of technology application in the gas detector industry
Gas detectors are generally divided into three series of products: gas leak detectors (referred to as "leak detectors"), gas alarm controllers, and gas detectors.
The "leak detector" is small in size, can be carried around or handheld, powered by alkaline batteries or rechargeable batteries, and can generally work continuously for nearly 12 hours. This instrument is mainly used for leak detection and line patrol of gas pipelines. If there is a gas leak, the leak detector will issue an audible and visual alarm and display the gas concentration at the same time, so as to take timely safety measures to prevent the occurrence of explosions and other malignant accidents.
The "detector+ controller", the most used detection instrument in industrial installations and in production processes, enables long-term monitoring of gas concentrations at explosion-proof sites. Most of these instruments are installed in oil depots, acetylene stations, liquefied gas stations and gas stations
gas detectorIndustry technology is reflected in the following two aspects:
1. The sensors used are different
Sensor technology involves light, heat, force, voltage, magnetism, gas, humidity, sound, rays, ions and other sensitive technical fields, in the past, due to the difficulty of physical isolation from the measurement environment of gas sensors, the technological maturity and industrialization lag of gas sensors have also been restrictedGas sensorand the practical application scope of gas detector instruments. In recent years, the continuous progress of technology, increasingly urgent market demand and huge market space have made the technology research and development and industrialization of gas sensors and gas detectors become a global hot spot, and the products are becoming more and more widely used. In the past, gas sensors were mainly used for the detection and alarm of gas in coal gas, liquefied petroleum gas, natural gas and gas in mines, but now the types of gases that need to be detected have expanded from the original reducing gases (H2, C4H10, CH4, etc.) to toxic gases (CO, NO2, H2S, NO, NH3, PH3, etc.). There are many types of gas sensors, which can be divided into three categories in principle: (1) Gas sensors that use physical and chemical properties: such as semiconductors, catalytic combustion, etc. (2) Gas sensors with physical properties: such as thermal conductivity, optical interference, infrared absorption, etc. (3) Gas sensors using electrochemical properties: such as current type, potential type, etc
2. The technical level of products is different
gas detectorThe production must meet the GBl5322-2003 standard. However, the GBl5322-2003 standard is only the minimum standard for gas detector production. Some products can only meet this standard. Some products add a lot of functions on the basis of this standard. For example, it has an early warning function to attract the attention of users in advance through early warning. Consider after-sales service issues in product design. In short, on the basis of meeting the GBl5322-2003 standard, there are great differences in the products of different manufacturers. This not only marks the difference in the technical forces of different manufacturers, but also represents the different understanding of products by different manufacturers.
3. The technology development trend of the gas detector industry
The current R&D and technological development of the gas detector industry mainly have the following directions:
(1) Extend the service life
Sensors are the key factor in gas detector products, but the service life of the sensor is the weakest link of the whole product, so how to improve the service life of the sensor to extend the service life of the product is the most concerned issue of product manufacturers, and the research work in this regard has been started.
(2) Enhance anti-interference ability
False positives and false positives are problems that gas detectors must solve. However, to completely solve this problem, it is necessary to have special technical personnel and a large number of test work to guarantee, in this regard some enterprises use multi-sensor solution, but this solution can not solve the problem of product service life, the fundamental method is to ensure the service life of a single sensor from the technical level. It can also ensure the use of a single sensor to achieve the selection of multiple air sources.
(3) Improve product intelligence
The current gas detector products can only realize the monitoring of a single household. With the advancement of technology and the requirements of monitoring, future Flammable gas detectors must be able to achieve networked monitoring. It is necessary to realize not only the monitoring of gas leakage, but also the monitoring of the product's own performance to ensure that all running products must be in good condition.
4. The competitive situation of the industry
The gas detector industry is in its infancy, and various industry norms are still being formulated, and the industry is mainly dominated by small and medium-sized enterprises, lacking leading enterprises.
The market concentration is very low, and the market share of TOP is less than 10%. The main competing brands in the industry include Henan Hanwei Electronics Co., Ltd., Insco Sensing Instruments (Shanghai) Co., Ltd., Shenzhen Tean Electronics Co., Ltd., Huarui Keliheng (Beijing) Technology Co., Ltd., Mei Sian (China) Safety Equipment Co., Ltd., etc.
Because the industry is still in the growth period of the industry, the scale of enterprises in the industry is relatively small, and there are few enterprises with obvious brand, technology, scale and other advantages. The main sales of each enterprise are concentrated in one or two industrial fields, covering the entire gas, petroleum, chemical, metallurgical and coal industries, and there are few enterprises with cross-field operating capabilities, and the competition of industry enterprises is concentrated in various sub-industry markets. There is a lack of enterprises with strong comprehensive strength, and there is only one listed company in China.
