Which multi function gas detector brand is better? Got it?

Tianjin Yalian Alarm Equipment (formerly Tianjin Dongli Alarm Factory) was founded in 1984 and is one of the earliest manufacturers of combustible gas alarm equipment in China. The main products are combustible gas detectors, combustible gas alarm controllers, toxic gas detectors, toxic gas alarm controllers, smart homes, smart alcohol testers, smart electronic products and other products.

Over the years, the product has been continuously improved, more and more specifications, has formed a series, has passed the national fire electronic product quality supervision and inspection center and the national explosion-proof electrical product quality supervision, inspection and testing center of the test and product type approval, with stable performance, high-quality service, reasonable, won the praise of new and old customers, widely used in petrochemical, pharmaceutical, storage, petroleum liquefied gas and other enterprises and institutions.

The first to recommend Yiyuntian! The multi-functional gas detector used in our factory is produced by them, which can accurately detect the concentration of gas, and has the advantages of real-time concentration value and standard signal output displayed on the spot, with the advantages of signal stability, sensitivity and high accuracy, and is suitable for various hazardous places.

Multi-functional gas detector, there is no say which brand is good, it depends on the brand suitable for their actual application, coal mine, gas, aerospace, transportation, marine environment, etc., there are different brands of special products.

Shenzhen Neurophth Technology, a professional manufacturer of gas detectors, has a unique gas cross-interference and compensation algorithm to solve the most troublesome gas interference problem directly from the source.

Brand ranking is a resource information classification method, which was first used within commercial organizations to select excellent partners by ranking competitors in the market. Now, this classification method is widely used in market research, and consumers can also use it to choose their favorite product brand. In the four-in-one gas detector market, there are many brands, different brands with different scales, different types of products, and different comprehensive performance and quality.

Therefore, there needs to be a leaderboard to guide you as to which brand of gas detector to choose.

It is well known that the common gas detectors on the market are carbon monoxide, carbon dioxide, oxygen and combustible gas detectors. According to different use occasions and needs, such as fire safety, industrial production, etc., different gas detectors need to be used. The most noteworthy gas detector brands on the market at the moment include:

Honeywell, Dr. Ger, Bacharach, and Industrial Scientific Corporation. These brands generally have a long history, a good reputation, and offer various types of gas detectors.

Among these four brands, Honeywell is the world's leading manufacturer of gas detectors, and its products are widely used in petrochemical, energy and power, safety and fire protection, environmental monitoring and medical and other fields. At the same time, Dr Ger was founded in 1889 and its products are used in a wide range of applications in the firefighting, chemical, oil fields, underground mines and other applications. Founded in 1909, Bacharach is one of the leaders in the field of flammable gas detectors for industrial and commercial markets.

Founded in 1985, Industrial Scientific Corporation is one of the leaders in the field of safe gas monitoring, and its products are widely used in the chemical, petroleum and mining industries.

To sum up, choosing a gas detector brand needs to be based on the specific situation. If you have special needs or a relatively high budget, it is recommended to choose Honeywell products. If you are looking for a product with a high performance** ratio and a good reputation, you can choose products from Dr Ger and Bacharach.

If you need a lightweight, easy-to-carry and easy-to-use detector, it is recommended to choose a product from Industrial Scientific Corporation. Therefore, when choosing a brand, you need to refer to your specific needs and find a gas detector brand that best fits your needs. <>

Portable gas detectors can detect more gases. It can detect combustible gases and toxic and harmful gases. 1. Combustible gas:

Such as hydrogen (H2), carbon monoxide (CO), methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), ethylene (C2H4), propylene (C3H6), butene (C4H8), acetylene (C2H2), propyne (C3H4), butyne (C4H6), hydrogen sulfide (H2S), phosphine (PH3), etc. 2. Toxic and harmful gases: chlorine, ammonia, nitrogen oxides, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide, dimethyl sulfate, nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene vapor, hydrogen cyanide, hydrogen sulfide, etc.

According to the classification of detected gases, there are flammable gas detectors, toxic gas detectors, common gas detectors, and special gas detectors; Among them, common flammable and toxic gas detection instruments** usually range from hundreds to thousands, while special gas detection instruments** range from tens of thousands. The advantages of common flammable and toxic gas detection instruments are cost-effective and good performance, while special gases meet special inspection needs and have high accuracy, but they are expensive.

According to the classification of the place of use, there are conventional type and explosion-proof type: the conventional type is produced in accordance with the national standard to meet the needs of all environmental use, ** in the hundreds to thousands, and the characteristic is that it is cost-effective. The explosion-proof type meets the needs of all inspections in special fields, and is slightly expensive.

According to the classification of the user group, there are household and industrial use: household gas detector ** in tens to hundreds of yuan, cost-effective and easy to use, only need to be placed in the designated position to plug in the power supply to work, and can be linked to the shut-off valve, to achieve automatic processing, the hidden danger from the source cut off. The requirements for the indicators of industrial gas detectors are very high, and they must meet the safety standards used in various places such as national standards and industry standards, ranging from hundreds to thousands.

According to the classification of functions, there are single detectors and multi-function detectors: a single gas detector is mainly used to detect a certain gas in the detection site, and the use is very large. The multi-functional gas detector has a six-in-one gas detector, a five-in-one gas detector, a four-in-one gas detector, a Kurek gas detector, etc., to meet the needs of different detected gas quantities.

According to the mode of use, there are portable (handheld) and fixed (mounted, wall-mounted): portable instruments that meet the pre-operation safety detection of gas for on-site operators, usually related to the use scenario. The fixed type mainly realizes long-term uninterrupted detection, so as to ensure the safety of the place, does not require on-site personnel control, and can be intelligently linked.

According to the classification of sampling methods, there are diffusion type and pump type: the use rate of diffusion gas detectors is very common, and ** is relatively low, ranging from a few hundred yuan to several thousand yuan. The pump-suction gas detector is relatively high, usually ranging from several thousand pieces to meet the needs of special places.

According to the classification of detection principles, flammable gas detection includes catalytic combustion type, semiconductor type, thermal conductivity type and infrared absorption type; Toxic gas detection includes electrochemical type, semiconductor type, etc.

There are different types of gas detectors.

According to the sampling method: there are two types: pumping type and diffusion type.

According to the mode of use: there are two types: fixed and portable.

According to the detection principle: there are ultraviolet principle, infrared principle, PID photoion principle, catalytic combustion principle and so on.

According to the number of gases detected: single and all-in-one.
