Calibration gases

Calibration gases are precisely defined reference gases and gas mixtures used to test and adjust gas detectors, gas analysers and similar instruments to ensure their accurate performance

We offer a full portfolio of calibration gases in Australia, including both a standard range and bespoke calibration gases made to suit unique requirements. As the country’s leading supplier of bulk and specialty gases, we have a great deal of experience in manufacturing all types of calibration gases to exact specifications and can guarantee the supply of products at a consistently high quality that meet all of your needs.

Whether you require a custom or standard calibration gas, we can manufacture it in any quantity you desire. From a single calibration gas cylinder to a large volume of cylinders for delivery on a regular basis, we can send what you need to any location in Australia or New Zealand.

We have the manufacturing capacity and the expertise to meet the requirements of organisations in a wide variety of industries. We are capable of producing quality calibration gases that are in full compliance with both your industry’s guidelines and government regulations.

  • How is calibration gas stored?

    The correct way to store a calibration gas depends on its composition but, in general, all cylinders should be stored upright and secured in such a way as to prevent them from being accidentally knocked over. The area in which they are stored should have adequate ventilation and should be dry, clean and cool. If you require detailed storage information, contact us or feel free to download the relevant safety data sheets for the gases in which you are interested in.

  • How much is calibration gas?

    Prices for calibration gases vary, according to the quantity and composition of the gases you require. If you would like to find out how much a certain quantity of a standard or custom calibration gas will cost, please call or email us at any time.

  • How long does a cylinder tank of calibration gas last?

    How long a single cylinder tank will last is dependent on the size of the cylinder tank and the flow rate required by the equipment you are using. If you have the flow rate figures at hand, we can tell you how long each size of calibration gas cylinder is likely to last you.

  • What is calibration gas used for?

    Calibration gases are used to calibrate analytical instrumentation such as gas analysers and detectors. We make calibration gases for a wide variety of applications, including air quality monitoring, automotive emissions testing, combustion control in power station burners and blood gas analysis.

  • Does calibration gas expire?

    This will depend on the composition of the calibration gas in question. The shelf life for most reactive calibration gases is from 6 months to 2 years, while non-reactive mixtures can normally be stored for up to 5 years.
