Gas Detection 
Calibration & Repair

To provide the right level of protection and early warning, portable and fixed gas detection systems need to be accurate & responsive to be effective. 

Why Calibrate?

Sensors can desensitise or drift over a short time, between <2% to <5% and will require service & re-calibration.

Who Can Calibrate?

Trained and certified, competent technicians.

How Often?

WHS regulations, Standards and similar documents recommend following the manufacturer's guide in relation to:

  • Daily function testing before use
  • Completing formal, documented calibration of instruments 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. We normally assess and quote within 24 hours.

We can even undertake a standard service & calibrate while you wait. Or we can come to you!

MSS has a fleet of service vehicles equipped for mobile service and calibration of multiple units at your site saving down time and expense.

What if my unit fails or needs parts?

If your unit indicates a fault or fails a bump test, it will generally require service which can include an accredited calibration and maybe even new components.
