Calibration gas mixtures are used to calibrate gas detectors and gas analyzers.

The mixtures come in compact cylinders of various volumes.

They can be taken into the field to calibrate portable and fixed gas analyzers.

Calibration gas can also be used to bump test gas detectors.

In a bump test we flow gas into the detector and check all its sensors, including the alarm levels.

Calibration gases come in a very wide range of concentrations:

From simple %LEL levels, through mixtures for laboratory use, down to low PPM levels and even % by volume.

A calibration gas cylinder can hold one gas or more; some special mixtures can hold as many as 20 different gases in one cylinder.

The compact disposable cylinders are 35 cm high and 9 cm in diameter.

This makes it possible to calibrate fixed detectors and analyzers in the field when they can't be brought to the lab.

What cylinder volumes are available?

60 liters

112 liters

12 liters

34 liters

Every calibration gas cylinder comes with the manufacturer's official calibration certificate to ISO and EN standards, traceable to NIST, the international standards body.

Steps for choosing a calibration gas cylinder and mixture:

Choose the concentration and type of calibration gas for the detector you want to calibrate (tip: the detector manufacturer's instructions say which mixture to calibrate with)

Choose the amount of calibration gas you need: 12, 34, 60 or 112 liters

Choose a suitable calibration gas regulator

Choose a suitable case for the cylinder and regulator
