As the name suggests, gas detectors are hand-held gas detection devices that sense the presence of various hazardous gas leaks in a wide range of industrial, domestic, and commercial safety applications. These portable devices detect a wide range of combustible and toxic gas leakage and provide an initial warning during risks with visual and audible alarms. Additionally, they are available in various designs and different sizes.
Why Are They Important?
Gas detection units are the inevitable devices for almost every place where they protect individuals from potentially toxic and fatal gases that could cause serious health hazards and even death. Furthermore, they also offer peace of mind through 24/7 monitoring. In addition, they are easy to carry with both fixed-to-wall and ceiling mounts.
What Are the Alternate Names for Gas Detectors?
These portable detecting devices are also called:
- Gas analysers
- Gas leak detectors
- Gas meters, and
- Gas sensors.
How Do Gas Detectors Work?
A gas detector consists of integrated sensors that sense the concentration of fatal gases in the air. An increase in the average concentration sets the alarms (audible and visual) to alert the individuals to trigger evacuation. A gas detector also alerts the operation departments within commercial or industrial buildings to make the people aware of the danger and to take preventive measures.
What Are the Types of Gas Detectors?
Gas detectors are classified into two types based on their gas detection technology and gas types. They include:
- Electrochemical gas leak detectors- designed to detect toxic gases.
- Catalytic and Infrared Sensors- suitable for detecting flammable or combustible gases.
The Following Types of Gases Are Detected:
- Ammonia Hydrogen Sulfide
- Butane
- Carbon Dioxide
- Carbon Monoxide
- Chlorine
- Methane
- Nitrogen Dioxide
- Oxygen
- Propane
- Refrigerants
- Sulfur Dioxide
Maintenance and Certification of Gas Detectors:
As most of these detectors are supplied with batteries, it is crucial to check them regularly for enhanced battery life and proper maintenance. Similarly, some models of these gas leak detectors come with ATEX certification (Atmosphere Explosible); an EU-regulated standard for product safety requirements in explosive environments.
