What is Gas Calibration?
Gas Calibration is the process of verifying and adjusting the accuracy of gas detection and measurement instruments—such as gas analyzers, gas detectors, and gas chromatographs—by comparing their readings to known concentrations of calibration gases. This ensures reliable and precise detection of gases for safety, environmental monitoring, and process control.
Why is Gas Calibration Important?
Gas Calibration is vital in industries like oil and gas, environmental monitoring, industrial manufacturing, healthcare, and laboratory research. Proper calibration prevents false alarms, ensures worker safety, maintains regulatory compliance, and optimizes operational efficiency.
- Ensures accurate gas concentration measurements
- Meets regulatory standards (e.g., OSHA, EPA, ISO 17025)
- Improves safety by reliable detection of hazardous gases
- Enhances process control and environmental compliance
- Reduces costly downtime and false alarms
What Equipment Needs Gas Calibration?
Gas Calibration is needed across a wide variety of instruments, such as:
- Portable and Fixed Gas Detectors
- Gas Analysers and Monitors
- Gas Chromatographs
- Combustion Analysers
- Environmental and Industrial Gas Sensors
Who Needs Gas Calibration?
Gas calibration is essential across industries where gas monitoring is critical to safety, quality, or compliance, including:
- Oil & Gas – Detecting flammable or toxic gases in hazardous environments
- Chemical & Petrochemical Plants – Monitoring gas levels during processing and manufacturing
- Pharmaceutical & Biotech – Controlling gas mixtures for sterilisation, incubation, or cleanrooms
- Mining & Tunnelling – Monitoring underground gas exposure and oxygen levels
- Laboratories & Research Facilities – Ensuring accuracy in gas chromatography and analytical testing
- Water & Wastewater Treatment – Monitoring gases like chlorine, methane, and hydrogen sulphide
- HVAC & Building Services – For indoor air quality and CO₂/CO monitoring
- Fire & Safety Services – Testing personal and portable gas detection equipment
- Environmental Monitoring Agencies – Measuring air pollutants and greenhouse gases
How Often Should It Be Calibrated?
- Every 6 to 12 months – Industry standard, depending on application and environment
- Daily or Weekly Bump Testing – For critical safety devices before each use
- After Sensor Replacement or Exposure to Harsh Conditions
- Before Audits or Regulatory Inspections
Follow manufacturer guidance and regulatory standards such as HSE, OSHA, ISO 17025, and ATEX.
