Carbon Monoxide Gas Analyzers CO

The carbon monoxide gas analyzer CO is in demand both at industrial enterprises and among public utilities. Its name already makes it clear what it is intended for - to detect and determine the concentration of carbon monoxide. Let's consider where exactly it is used, what principle it operates on and what characteristics a gas analyzer for measuring CO should have so that you can choose the most suitable model.

 

Why Carbon Monoxide Is Getting Increased Attention

 

CO, or carbon monoxide, is very dangerous for human and animal health. Inhaling its vapors leads to severe poisoning and even death (if its concentration in the air of a closed room is too high).

Moreover, physically, CO is a colorless gas that has no odor - it is impossible to detect it with the naked eye or smell it.

And such a dangerous substance is emitted during the operation of heating stoves, boilers, gasoline engines, when burning coal, wood and other types of solid fuel. Accordingly, wherever this happens, a carbon monoxide (CO) gas analyzer should be used - a device that detects the presence of harmful gas, determines its concentration in the air and signals if it is above the norm. It is impossible to overestimate the relevance and importance of such a meter - safety, health and even life depend on it.

 

Key Features of the CO Gas Analyzer

 

Such popular devices have long been produced in a variety of designs. There are stationary CO gas analyzers installed at large industrial enterprises and representing complex equipment. There are portable devices - lightweight and compact with clear displays.

Models can differ dramatically from each other. Therefore, it is not entirely rational to consider the operating parameters of a particular device - it may turn out that in your case a completely different meter is better suited.

But there are characteristics that are important for any carbon monoxide gas analyzer, and these are:

• measurement range — the wider it is, the more versatile the device;
• accuracy — the lower the percentage of error, the better;
• sensor type — electrochemical sensors perform well when working with gas mixtures;
• resolution — the higher it is, the smaller the leaks the device detects;
• display size — the wider the diagonal, the clearer the results;
• notification type — visual, sound, combined.

And each additional function of the gas analyzer for measuring CO will also be a plus. Start without zeroing, the presence of sensors, temperature indication, self-test mode, backlighting and user calibration - these and other options expand the possibilities of use.

Where are carbon monoxide analyzers used?

 

In general, in all places where some fuel is burned and the emission of harmful substances is theoretically possible. More specifically, various gas analyzers for measuring CO are used at the following sites:

• residential multi-apartment buildings, country houses, summer cottages;
• boiler rooms and heating rooms;
• production shops of metallurgical and chemical plants;
• office buildings, places with high traffic;
• catering establishments;
• closed parking lots and service stations.

 

These facilities usually have stationary CO gas analyzers installed in each separate room of the premises.

There are facilities where portable carbon monoxide gas analyzers are usually used:

• smoke zones;
• places with high fire hazard;
• garages and auto repair shops;
• personal and public transport.

Often not constantly, but when a leak has already occurred and it is necessary to record the exact content of a harmful substance in the air.

 

What is the principle of operation of a carbon monoxide gas analyzer?

 

The sensor measures the concentration of the mixture components. And turns on the alarm if the percentage of carbon monoxide exceeds the norm. You receive an audible and/or visual alert and can leave the premises in a timely manner, taking all necessary safety measures (opening the doors, turning on the ventilation).

As you can see, the CO gas analyzer works very simply. In principle, this is not the most complex equipment. And both of these factors have the most positive effect on the reliability of the device and ease of use.

How to choose a CO gas analyzer

 

To buy the most suitable model, think and answer yourself where and in what format you will use the device. If all the time in the same place, a stationary CO gas analyzer is better, if at different sites, you will need a portable one.

If you give preference to a mobile device, decide what kind of power it will have. A battery-powered device will be as autonomous as possible, but will work longer on a battery (without recharging). And a carbon monoxide gas analyzer powered by an outlet will outdo both of them, but it will not record anything in the event of a power failure or power outage.

Think about the alarm - a combined one is more convenient than just an audible one - and about the clarity of readings. A modern gas analyzer for measuring CO simply must have a display with a sufficiently wide diagonal. And the more additional indicators, such as ambient temperature, are displayed on the screen, the better.

When buying a carbon monoxide analyzer, make sure that the seller provides you with a truly original device (he must show a certificate of conformity). Remember, you need a high-quality, accurate, durable meter.

 

Differences from carbon dioxide (CO2)

 

Carbon dioxide (CO2) and carbon monoxide (CO) are two different gases, each with unique physical and chemical properties, as well as different effects on human health and the environment.

At normal atmospheric concentrations, carbon dioxide is non-toxic and is an essential part of many life processes (e.g. photosynthesis). However, at high concentrations, CO2 can cause suffocation, headaches, rapid breathing, and other symptoms of hyperventilation. However, carbon monoxide is highly toxic and can be fatal even at low concentrations.

CO2 is produced by the combustion of hydrocarbons, the respiration of living organisms, and has a wide range of uses. Carbon dioxide is used in beverages (for carbonation), in fire extinguishers, for welding, in greenhouses to stimulate plant growth, and in other industrial processes, while CO, due to its toxicity, does not have many direct uses, but is an important intermediate in some chemical processes.

In terms of safety measures, CO2 gas analyzers are used to measure carbon dioxide concentrations, especially in industrial and commercial settings. These devices provide accurate and reliable measurement of CO2 levels, which is especially important for air quality monitoring, ventilation control, and industrial process control.

Basic principles of operation of CO2 gas analyzers

 

CO2 gas analyzers typically operate on one of several principles:

• Near Infrared Absorption (NDIR): The most common method for measuring CO2, it is based on its ability to absorb infrared radiation of a specific wavelength. Devices with NDIR sensors emit light through a sample and measure the amount of light absorbed by the carbon dioxide. This method is highly accurate and reliable.
• Chemical Sensors: These devices use chemical reagents that change their properties (e.g. color) in the presence of CO2. Chemical sensors are easier to manufacture, but are usually less accurate and require regular calibration and replacement of reagents.
• Biosensors: This is a relatively new method that uses biological materials to detect CO2. Biosensors can provide high specificity and sensitivity, but their use is limited due to difficulties with sustainability and standardization.

Applications of CO2 gas analyzers

The CO2 analyzer provides precise control and monitoring of carbon dioxide levels in a variety of environments and is used to control air quality and ventilation systems in industrial and domestic premises.

In the food and beverage industry, meters are used to control fermentation and packaging processes, where CO2 levels can affect the quality and shelf life of products.

In scientific research, carbon dioxide analyzers have found their application in the study of climate change, monitoring greenhouse gas emissions and studying the natural carbon cycles in ecosystems.

In addition, devices are used to monitor CO2 levels in greenhouses, where control of this gas concentration can contribute to more efficient plant growth.
