Calibration gas 5-gas mixture for bump testing, 60 litre
Dräger calibration gas containing a five-component mixture of hydrogen sulphide, carbon monoxide, carbon dioxide, methane and oxygen in nitrogen, in a 60 litre disposable cylinder at 35 bar – for bump testing and calibrating five-channel monitors including the CO₂ channel.
- A bump test is what makes a reading defensible – a gas detector that has not seen test gas since its last service is an assumption, not a measurement, and most confined space procedures require the check to be recorded before entry.
- Certified mixture with a stated shelf life – each cylinder carries its composition and expiry date, so the calibration record can be traced back to a known reference.
- 60 litre cylinder at 35 bar – the standard Dräger disposable format, sized for routine testing in the workshop or the calibration station.
- Five channels including CO₂ – the added CO₂ component covers instruments configured for landfill, brewing, water treatment and other work where carbon dioxide is a risk in its own right.
Gas composition
- 15 ppm hydrogen sulphide (H₂S)
- 50 ppm carbon monoxide (CO)
- 2 vol% carbon dioxide (CO₂)
- 2.5 vol% methane (CH₄)
- 18 vol% oxygen (O₂)
- Balance: nitrogen (N₂)
Also required for measurement
- A pressure regulator or demand flow regulator suitable for this cylinder – the cylinder is supplied without one, and the regulator must match both the valve and the flow rate your instrument or test adapter needs.
- A bump test adapter or calibration cradle for the instrument being tested.
Important information before use
- Observe the expiry date printed on the cylinder; the stated accuracy of the mixture is not maintained beyond it.
- Store and transport the cylinder upright, below 50 °C and out of direct sunlight, and vent it before disposal in line with local regulations.
