From a simple single channel gas detection panel to advanced addressable multi-channel systems with adjustable alarm levels, multi-relay outputs and even combined with gas pressure proving solutions for most requirements.
Capable of connection to a mixture of gases, we have it covered.

Please don’t hesitate to contact us as we are constantly expanding our detector range and would be happy to discuss any requirement you may have even if your target gas is currently listed. Just give us a call on +44 (0)161 233 0600.
All gases will mix with all other gases over time. They will generally not separate out. Some gases could react chemically with each other on mixing.
Air has an equivalent molecular mass of about 29 and that corresponds to air density at sea level at 15c of 1.225kgm-3. For instance, a gas with a molecular mass lower than 29 will be lighter than air. So a gas or gases mixed with air that is lighter than air will still be lighter than air but less so. They will still tend to rise until they become so diluted (over a given time) with fresh air that the effect will become negligible. The same applies to gases that are heavier than air through with the opposite effect of sinking, see the guide below which will help you.
Consideration should be given to temperature in so far as a release of a gas is hotter than the surrounding air may initially rise even if the density of the gas is greater than 1.22kgm-3. The converse applies where the release of gas is colder than the surrounding air.
At best, gases, with the exception of oxygen or air, are potentially asphyxiants due to the dilution of Oxygen (O2) in the air. Other gases vary from mild to extreme toxicity.
