Device Gas analyzer It is a device that is used to detect, detect and display the amount of polluting gases and flammable gases and to detect gas leaks from tanks or chambers such as Co and Co2 gases. Usually Gas analyzersThey have the ability to connect to a computer and perform various analyzes, and in some cases have a pressure difference sensor.
Solids or liquids emit toxic fumes due to excessive heat, which makes the environment dangerous. These gases act very much like breathing air and are not released from the atmosphere. Poisoning caused by these gases, if not treated in time, can cause death or damage to parts of the respiratory and nervous systems. Toxic gases, because they enter the body through inhalation, easily enter the bloodstream and after a few seconds, they reach the nerve centers and have severe effects.
These toxic gases include carbon oxides, sulfur oxides, nitrogen oxides, hydrocarbons, and oxidizers. Since a specific formula or method cannot be used to discover them, and a specific method must be used for each of them, a device called analyzer Analyzer is used.
How to detect, detect, and detect all kinds of vapors, liquids, and particles scattered in the air is used more seriously by chemists and military industry experts. Gas detectors are designed to continuously monitor the physical and chemical phenomena of gases in the shortest possible time and in the early moments of dangerous gas leaks, automatic alarms and at a more advanced level to control safety and security equipment and prevent accidents. For example, on the battlefield, detectors are needed to respond to chemical agents, in any form and condition. In such cases, any warning about the chemical toxins used and the identification of their type can prevent a catastrophe.
Types of gas analyzers
Gas analyzersAccording to the type of consumption, they are divided into the following two categories:
1– Ambient gas analyzers
Ambient gas analyzers They are divided into two parts: industrial environment and clean air, the first part includes Gas detectors And the tube detector and the second part include fixed and mobile stations.
2. Combustion gas analyzers
Combustion gas analyzers They are also divided into two parts: industrial chimney exhaust and car exhaust exhaust.Chimney output analyzers Industries are both fixed and portable, whose portables, in addition to being used in military industries and wars, have special applications in the oil and gas industry.
The main components of a gas analyzer
In general, any analyzer It consists of several parts, the most important part of which is its sensor, which is responsible for detecting the desired indicator. The information obtained by the sensor is in the form of analog data, which is usually converted by Conditioning Circuits to a range of values understandable for analog to digital converter circuits or processors. After digitization, the information is sent to the detector’s internal microprocessors for processing, and after analyzing this information and receiving the desired result in this section, the output is transferred to the data circuits to be sent to the processor and the overall controller of the system. The data is converted and sent to different communication protocols.
In determining the type of gas, the choice of sensor depends on the type of application and the expectations of the system. If the type of gas sensor and detector is selected improperly, the operation of the whole system will be disrupted. It should be noted that each sensor has its own advantages and limitations. Therefore, incorrect selection of the sensor will lead to the possibility of leaving the proper operating range and facing limitations and sometimes inaccurate and untimely outputs.
Gas detection detection in this Analyzers It can be done in different ways:
• Analyzer with Ultra Violet signal lamp
• Analyzer with electrochemical sensors
• Infrared analyzers
• Catalytic analyzer
Important points in choosing one Gas analyzer

• Ability to measure different gases (O2, CO, CO2, NO, NO2, SO2, HC)
• Measuring range for each type of gas
• Ability to measure differential pressure
• Ability to measure pressure and gas velocity
• Probe type
• Ability to connect to a computer and store information
• Ability Direct printing
