Using Gas Detector To Detect Hazardous Gas

A useful instrument to save life


Gas Detector Singapore

When selecting a gas detector in Singapore it is important to have a reliable and robust gas detector Singapore supplier can provide.When the gas detector displays an inaccurate reading, it puts you and your workers at risk. Perhaps you are working around the gas tank and pipelines that emit gases or you work in a confined space, an industrial plant or in underground utilities. Regardless of the environment, if the gases or vapours are escaping, it is important you have a gas detector that registers accurate readings.

Types of Gas Detector

There are various types of gas detectors available in the Singapore market but their functions are quite similar. Those that are commonly used are:

  • Carbon Monoxide gas detector
  • Carbon Dioxide gas detector
  • Multi-gas detector
  • 4 in 1 gas detector
  • Methane detector
  • Portable gas detector
  • LPG gas detector

Carbon Monoxide Gas Detector

Carbon monoxide (CO) is a toxic gas that cannot be seen or smelled by the human senses. It is completely invisible and is a highly toxic gas.  It is termed a toxic (blood) asphyxiant, meaning it reduces the oxygen transport properties of the blood. A low ppm doses of it can cause dizziness and headaches. If the victim is moved to fresh air area, there will be no permanent damage. However, high concentrations of it can saturate a person’s blood in a matter of minutes and quickly lead to respiratory arrest or death. It is vital to have a carbon monoxide detector that can alert you if it detects that the said gas is present.

Carbon Dioxide Gas Detector

Carbon Dioxide (CO2), in an excessive amount, can displace oxygen in the air and cause suffocation. The gas can accumulate in confined places or low-lying areas, especially those without sufficient ventilation. A Carbon Dioxide Gas Detector is necessary to monitor the presence and level of carbon dioxide to prevent exposure leading to irreversible health effects.

Gas Leakage

Certain work and industrial environments involve processes that may result in gas leakage can be harmful. The most common gases produced are carbon monoxide, chlorine, hydrogen fluoride, ammonia and flammable substances. Typically, these gases are found in the production of iron and steel, chemicals and petrochemicals, oil refining, refrigeration and water treatment.

Instruments that can sense these escaping gas fumes include gas detectors and gas analysers. Specifically, gas detectors alert you to conditions outside normal parameters with an alarm. Gas analysers can sense the concentration or quantity of a gas within a mixture of gases.

To remain effective, your gas detector or gas analyser calibrated are calibrated by factory-trained technicians to verify proper operation.

Why are readings not accurate?

The reasons for the inaccuracy of the gas detector include:

  • Age of the sensors, which normally degrade over time
  • Exposure to extreme temperature and humidity
  • Exposed to high level of specific gases
  • Harsh storage and rough handling conditions (including being dropped or submerged in liquid)

Ensure worker safety by having your gas detector or gas analyser calibrated by factory-trained technicians to verify proper operation.

What is Gas Calibration?

Gas Calibration is resetting the response of the detector against a known concentration of gas. We use a calibration gas which enables us to determine the relationship between the reading recorded by the detector and the concentration of gas that it is designed to alert us to. The frequency of the calibration is set by the manufacturer.

Why do we calibrate the gas detector?

The reasons are due to:

  • wear and tear our gas detectors take a fair amount of abuse each day they’re used. From exposure to extreme temperatures and humidity to “sensor poisoning” from external contaminants such as oil, grease, silicon, etc
  • knocks and bumps all of these can affect the accuracy of the detector.
  • the regulatory requirement the device itself keeps a log of all calibrations, future calibration dates etc. This will keep us in line with the relevant regulations of our employer, workplace or country of employment.
