About this item
To measure the 'spot concentrations' of nitrous fumes 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.
Cross sensitivity: Chlorine and ozone are indicated as well but with different sensitivities. However for tube 20/a, there is no indication below the TLV for these chlorine and ozone, but higher concentrations are 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.
* Desorption strokes in clean air
