Portable gas detector calibration

Single gas, multi-gas and area monitors, from the Point Safety gas specialists.

Portable gas detectors serviced and calibrated by the Point Safety team, gas detection specialists since 2011. For fixed systems, visit Point Safety.

All calibration is traceable to national standards and carried out under our ISO 9001 quality management system.

Instruments we calibrate

  • Single gas detector, standard
  • Single gas detector, exotic
  • Multi-gas detector, standard
  • Multi-gas detector, exotic
  • Area monitor

Why portable gas detectors need calibrating

A portable gas detector is life-saving equipment. Electrochemical and catalytic sensors lose sensitivity over time and can be poisoned by some substances, so a detector can look fine and still fail to alarm at the right level. Regular calibration with certified test gas is the only way to know it will respond when it matters.

Calibration Point is run by the Point Safety team, who have specialised in gas detection since 2011.

How often should a gas detector be calibrated?

Most manufacturers recommend a bump test before each day's use and a full calibration at least every six months. Some site rules or manufacturers set shorter intervals. A detector that fails a bump test should be calibrated before it is used again.

What you get back

  • A calibration certificate showing the instrument and each sensor
  • The test gas concentrations used and the readings before and after adjustment
  • Alarm function checks
  • A statement of traceability to national standards and the next due date

All work is carried out under our ISO 9001 quality management system. UKAS-accredited calibration is available on request through our UKAS-accredited partner laboratory.

Common questions

What is the difference between a bump test and a calibration?

A bump test briefly exposes the sensors to gas to confirm they respond and the alarms work. A calibration adjusts the readings against certified gas so they are accurate.

What if a sensor needs replacing?

We quote for any sensor replacement or repair before carrying out the work.

Do you work on fixed gas detection systems?

Yes, through Point Safety, who install, service and calibrate fixed gas detection systems.
