To measure the 'spot concentrations' of nitrogen 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.
- Within their TLV, ozone or chlorine do not interfere with the reading
- Higher concentrations indicated however with differing sensitivity period
- Nitrogen monoxide is not indicated
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.
