Service & Calibration
Gas Detection

gas detector calibration

Gas detector service and calibration is an essential part of safe work practices for keeping workers in industries and workplaces where their safety relies on gas detection devices to protect from being exposed to high concentrations of a wide range hazardous gases, vapour and chemicals.

Portable & fixed gas detection devices serve as the first line of defense against potentially life-threatening situations by alerting users to the presence of harmful gases, providing early warning and monitoring of exposures.

Why Calibrate?

Regular gas detector service and calibration is a quality safety control measure, enhancing the accuracy and reliability of these devices. Inaccurate readings can lead to a false sense of security or worse false alarms which undermines the confidence of the operators.

Sensors de-sensitise or “drift” over a short time, even when not in use, between <2% to <5% and will require service & re-calibration.

Who Can Service Gas Detectors?

Trained and certified, competent technicians according to mnufacturers instructions and EN60079.
MSS Safety is a level 2 MSA Safety technical service partner and provides warranty parts and replacement parts as authorised by the factory.

Gas Detector Calibration – How Often?

WHS regulations, Australian Standards and similar documents generally recommend calibrating units weekly or monthly until a medium is found which means the units are working effectively. Good practice would include referencing the manufacturer’s instructions for use, which in most cases recommends a maximum interval of six months and provides a guide in relation to:

  • Daily function testing before use
  • Completing formal, documented calibration of instruments regularly or at least every six months (IEC60079/AS/NZS60079)
  • Set up and monitor a gas detection program, including trained personnel to regularly check, monitor and document equipment and personnel
  • Australian WHS regulations specify equipment must be used in accordance with manufacturers guidance.


  • You can bring or send your equipment to your nearest MSS SAFETY office location. We normally assess and quote within 24 hours.

Manufacturer Authorised Service (EN60079.29)

MSS Safety is a technical partner for MSA Safety, Status Scientific and Inte Electrical and is authorised to complete service calibration and high level warranty repairs. We provide service on most brands in partnership with the manufacturer.

MSS Safety’s qualified technicians are able to provide basic to intermediate levels of service including calibration, installation of plug & play replacement parts in accordance with the manufacturers instructions for use.

Where a higher level of service is required that could effect certification of the equipment, (e.g. resoldering boards or hard wired components), to meet the requirements of AS/NZS (EN60079), MSS partners with the manufacturer directly or their local agents for back to base service to maintain certification and warranty.
