Gastec Dosi-Tubes
a1-cbiss are the master distributor of Gastec gas detector tubes in the UK and Europe.
The passive Dosi-tube system allows an operator to evaluate the level or exposure of hazardous gas / vapours to a worker over the Time Weighted Average (TWA). Dosi-tubes are clipped into a dosi-tube holder (bought separately) which attaches to an item of clothing and worn over a working day or shift. The dosi-tube is a direct read tube which shows a colour stain to determine how much hazardous gas a worker has been in contact with over the given period. There are 10 tubes per pack.
