What are Gas Detectors?

Gas detectors (also known as gas monitors) refer to a category of instruments that are used to detect the presence or absence of one or more kinds of gases in an area. So for example a Carbon Monoxide gas monitor in your home is used to warn you when excess levels of CO are detected. In many industries, such as Oil and Gas, Chemical, Power generation, Pulp and paper and Mining, many workplaces may have presence of hazardous gases that are toxic and or explosive, for example Hydrogen Sulfide. Such places use portable h2s gas detectors, explosive gas detectors to know in advance the ambient levels of poisonous gases in the area. On the other hand some gases like Oxygen are essential for us to survive and Oxygen gas detectors and meters are used to confirm that the area is suitable for entry. For example for entering a sewer pipeline for maintenance work, we must use the toxic gas detector (for example a portable h2s detector) as well as an Oxygen gas detector to find out if the area is safe for entry. We may also have to equip ourselves with a personal gas monitor that can measure the current levels of h2s and oxygen to warn us to get out if the hydrogen sulphide level is higher than safe or if the oxygen level falls to a low level.


Why this Gas detector Training Course?

Abhisam is the global pioneer in creating e-learning self paced courses for engineers and technicians all over the world. Gas detection and gas monitoring is a niche subject, but very critical for any Instrumentation & Control Systems engineer, Automation Engineer or technician and a Safety Engineer to understand. This is because there are many different types of gas detection techniques such as catalytic combustion, semiconductor, infrared and so on and each one has its own advantages and disadvantages. It is essential for any engineer to know the specific capabilities of these gas sensors to select and install the correct one, as also to understand how to calibrate and maintain them.

Gas Monitors Training Course- Customer Testimonial

This is the best course I have come across in Gas detection systems. I am working in an Oil & Gas processing plant.
After completing this course, I have got lot of confidence in the system.
The information that we learn can be directly applied in our day to day operations.
The course is well written in a simple language without missing the essential information.
The information that we learn in this course cannot be learned even in a regular “fire and gas systems course” which costs multiple times than this. It is very useful for engineers who are working in design and operation & maintenance as well not to exclude sales.

Why should I buy this course? Is it a Power Point Presentation or a Video?

No, it is not a Power Point presentation or a video of a guy speaking. It is a full fledged self paced e-learning course with animations and simulations to explain key concepts. You will easily understand for example how an Infrared gas detector works or how a catalytic combustion detector works. There is an old saying that “A picture is better than a thousand words”. Well an animation is much better than a 1000 pictures. You can see some examples of it in the Demo. But there is really nothing like it anywhere else.

This training course has several modules (you will spend about 10 hours to complete all of them) that have text, animations & simulations to explain key concepts, situational videos, real life videos of how to test a Chlorine gas monitor and so on. After you complete this course you can take the associated exam and earn a Certificate of Competency and an electronic badge via Credly.

Why can’t I get this for free?

You can of course trawl the internet and search for information but much of this course is created by our experts and is not available online anywhere else. One of the problems with the internet is that for general topics, there is a flood of information and you have tons of it. For specialized and niche topics, there is a lot of information but much of it may be either not authentic, or could be opinions presented as facts, or pure marketing hype or completely outdated. Theoretically you may be be able to search for everything and compile it and understand it, but you will likely spend at least a year doing it. You surely value your time, do you not? On the other hand, you need to only spend on this course, 10 hours of your time in going through it and then you can always earn a Certificate of Competency plus an electronic badge.

The material in this course is presented in a very structured and logical manner, so one thing leads to the next and you will have several “Ah-Ha!” moments. We do not think you could ever find all this information free on the internet.

Can I not buy a book?

You will not get all this information in a single book, you will have to buy several. Then, a book will not have animations, so it is kinda hard to understand. However even if you take one look at the animated workings shown in the Abhisam e-learning course, you will understand in a jiffy. Books may be having obsolete information, so that is not a viable alternative to a real training course.

Lastly nobody will issue you a certificate because you read a book.
