To measure the 'spot concentrations' of perchloroethylene 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.
Other chlorinated hydrocarbons, free halogens and hydrogen halides are also indicated. Petroleum hydrocarbon vapors result in a shortened reading.
One stroke is equivalent to a volume of 100 ±5 ml of gas passing through the tube.
The standard measuring range is calibrated at 20 °C and 1013 hPa.
