To measure the 'spot concentrations' of hydrochloric acid in the air 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.
- Hydrogen sulphide and sulphur dioxide do not interfere in the TLV range
- Impossible to measure hydrochloric acid in the presence of other mineral acids
- Chlorine and nitrogen dioxide are indicated but with different sensitivities
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.
