Some entries will involve a requirement to monitor exotic or precise gas levels. These units offer a facility to use multiple cells that may fulfil your requirement.
The unit can be configured with as little as one cell fitted for instance in the case of carbon dioxide, but may also have other cells fitted. These units normally range from 4 to a 6 cell possible configuration although care must be taken as some cells are cross-sensitive.
Should you prefer we have gas detectors with IR available for hire.
