Oxygen Analyzer Features and Uses

What is an Oxygen Analyzer?

It is a device that measures the level of oxygen in a system therefore determines if the level needs to be increased or not. Oxygen analyzers in turn use a kind of oxygen sensor for their functioning. An analyzer uses a sensor cell constructed of ceramic materials to measure the oxygen level. Recently since industrial, vehicular, or rather all types of emissions are given more emphasis so as to decrease pollution, industrial users want the analyzers to be more accurate in the measurements and repeatable in terms of usage. Regular users of oxygen analyzers also want it to be more calibrated and in need of less maintenance. There are various types of oxygen analyzers and users have a wide range of choice from the following:

• Ambient temperature-Oxygen Analyzer
• Electrochemical-Oxygen Analyzer
• Paramagnetic-Oxygen Analyzer
• Polarographic- Oxygen Analyzer
• Zirconium Oxide- Oxygen Analyzer.

The ambient temperature electrochemical sensor is also referred to as a galvanic sensor which is small, partially sealed, cylindrical device which contains two dissimilar electrodes immersed in an electrolyte. The oxygen molecules diffuse in the electrolyte and that results in a chemical reaction that generates a certain amount of current that tells us the level of oxygen in the system. Similarly Paramagnetic analyzer works on a simple principle that oxygen has a very high magnetic susceptibility and shows a paramagnetic behavior. Polarographic analyzers work well in case of percent measurement and the main advantage is that when it is not operative, there is no consumption of the electrode. It can be stored for longer duration of time.

Uses of Oxygen Analyzer

Oxygen analyzers are used for combustion monitoring and keeping a control over it in a range of applications and help the industries to achieve considerably in saving energy. The applications of oxygen analyzers vary from energy-consuming industries to various combustion facilities. It is used in industries such as iron and steel, electric power, oil and petrochemicals, ceramics, pulp and paper, food and textiles and in facilities such as incinerators and small or medium sized boilers. Besides, monitoring and controlling the analyzer also helps in lowering the amount of carbon dioxide, Sulfur dioxide and Nitrogen oxides in the emissions by resisting the incomplete combustion of fuel, therefore preventing the world from global warming and air pollution.

Features Of Oxygen Analyzers

Oxygen Analyzers have advanced solid-state sensors, which help to get a very high precision measurement of oxygen. It also measures the part of oxygen per billion to hundred percent, thus there is no need to get another instrument to do that. With the help of one instrument only all the information can be received. Oxygen analyzers have the ability to respond very quickly, in fact in milliseconds, which not only saves time and increases efficiency but also provides the facility to track the process conditions competently and methodically. The oxygen analyzers have a non depleting sensor most of the time which performs well for a long period of time thus saving you the time and energy to research on a new analyzer or sensor and money to invest in a new one. The outputs provided by the analyzer are user scalable and analogous, which have the ability to define the concentration range of interest in a better way. There are dual user adjustable alarms, which set critical process limits. A Microprocessor Controller is also present which helps in ensuring dependable and accurate readings. There is also a built in sample by-pass gas which helps to promote rapid transport of the sample gas. Most of the analyzers are very compact and durable. They are easy to operate, splash proof, they have a built in flow restrictor and the sensor and battery replacement are also easy to do. The battery time is expected to be two years. AAA batteries are used which are inexpensive and easy to use. With some of the cases a deluxe carrying and storage case also comes which makes it convenient to carry if you have opted for a portable oxygen analyzer.
