The evolution of gas detectors
The portable multigas detection instrument is widely relied upon throughout the world to protect its wearers from the hazards caused by various toxic and flammable gasses no matter where they are or what they are doing. For many applications the instrument configuration is most commonly flammable, carbon monoxide, hydrogen sulphide and oxygen deficiency.
Detection of these four gases covers applications in industries such as oil and gas, chemical, utilities, steel, manufacturing and the fire service. To be an integral part of the safety process in these industries an instrument has to be compact, lightweight, tough and easy to use. Once the gas configuration has been decided upon the type of instrument used has to be considered.
In the past multigas detectors were large, heavy, cumbersome devices which had to be worn on a shoulder strap for the main reason that they were far too large to be worn on a belt. As technology progressed so did customer requirements and the main goal was to make instruments more compact.
