To measure the 'spot concentrations' of hydrogen peroxide 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.
It is impossible to measure hydrogen peroxide in the presence of chlorine or nitrogen dioxide. Only hydrogen peroxide vapour is indicated, not the aerosols.
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.
