How Frequently Is Gas Analyser Calibration Required?

Gas analysers are important tools for ensuring that dangerous appliances are kept safe. Whether it is in a domestic or business setting, a gas analyser will measure the carbon dioxide and carbon monoxide emissions of a range of appliances to ensure that they are operating safely.

It is therefore essential to ensure that these analysers are fully calibrated in order for them to deliver accurate results. In this article, CEM Solutions look at the importance of gas analyser calibration and how often it should be taking place.

[edit] What is a gas analyser?

Combustion based appliances such as stoves, boilers, generators and furnaces in commercial and domestic settings, can be responsible for a number of emissions. These have the potential to be extremely dangerous, and so a gas analyser is needed to help measure the extent of these emissions. They are capable of measuring a number of critical gases, including carbon dioxide and carbon monoxide.

The analyser will check whether these are being emitted while the appliance is in operation and alert the operator straight away so that any appropriate action can be taken in order to keep people safe.

In addition to this, a gas analyser can also measure the ambient air temperature and oxygen levels to ensure that the appliance has the correct level of ventilation and that the conditions in the room are safe for use.

[edit] Calibrating a gas analyser

A gas analyser is an incredibly important tool as it plays a key role in safety. As it is continually exposed to gas, it is likely that sensors and components will deteriorate over time which could lead to false or inaccurate readings. This can have massive safety implications as unsafe appliances may go undetected.

It is for this reason that gas analysers need to be regularly calibrated and checked to ensure that they are always working correctly. In order to calibrate a gas analyser, it will be exposed to different gas mixtures so that each part can be properly tested. Individual components will also be assessed to determine whether they are fit for purpose.

[edit] Gas calibration frequency

Many gas analysers are able to warn you that a calibration is due, which will allow you to stay on top of any calibration schedules. As a general rule, gas analyser should be calibrated at least once a year.

However, if it is something that is used heavily then you should be looking to do this on a more regular basis. It is also important to remember that if you believe the analyser is faulty at any point, you should have it checked immediately and not wait until the next part of the calibration cycle.

It is important to remember that the calibration process can take a number of days, so this needs to be taken into account when planning your calibration schedule. You may want to stagger the calibration of your devices if you have multiple gas analysers to ensure that you are not left without one for any period of time.

[edit] Why does regular calibration matter?

Ensuring that your gas analyses have been calibrated is essential for both safety reasons and legal compliance for your business. The calibration is particularly important to ensure that your business adheres to strict safety standards and a failure to do so could result in a loss of your licence to operate.

It is also important to note that using a gas analyser without a valid calibration certificate may constitute a criminal offence. Putting together a thorough calibration schedule can ensure that your devices are checked on a regular basis and remain safe and functioning properly at all times.
