Gas detection tubes for sulphur dioxide
Gas Tubes
To measure the 'spot concentrations' of sulphur dioxide for use with an Accuro® pump.

Uses include determination and measurement of concentration peaks, personal exposure in the inhalation area, detection of leaks in pipelines or gas installations, air analysis in sewers, shafts and confined spaces.

The tube sulphur dioxide1/a has a prelayer so that H₂S in the TLV range is retained and does not interfere. Hydrogen sulphide and acidic gases may interfere with other tubes.

One stroke is equivalent to a volume of 100 ±5 ml of gas passing through the tube.
