Calibration Gas

Calibration Gas

Argon C02 Gas

Calibration gases are split into two categories. These are zero calibration gas and span calibration gas. Calibration gas is used to calibrate gas analyser's. Calibration gas is in addition used to calibrate Gas detectors. These Gases will also be known as Span Gas and come in a Span Gas cylinder. This product has added one or more component(s). Zero calibration gas is a gas that does not contain flammable gas. You will need this gas in the calibration of analyser's or gas detectors. Span calibration gases are a more advanced type of calibration gas. They contain a more precise total make up of detectable gases. Quad gases are mainly used within Marine environments. Quad gases are a four gas mix.

Supplied in a range of lightweight cylinders and made from aluminum. Both reactive and non-reactive mixtures are available. There are no rental charges on the cylinders. A large range of Calibration Gas regulator(s) are available from stock. Carry cases to compliment the cylinders are also available. The cylinders are non-refillable.
