To provide the right level of protection and early warning, portable and fixed gas detection systems need to be accurate to be effective. 
Even with current technology, sensors can drift over a short time as much as <2% to <5% and will require service periodically by qualified personnel, even if using automated calibration equipment.

 How Often?

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. 

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
  • WHS regulations specify equipment must be used in accordance with manufacturers guidance.
