Sulfur Dioxide Diffusion Tubes
Ambient air monitoring using our Sulfur dioxide diffusion tubes is a simple means of monitoring that requires no further maintenance after installation – an easy, cost-effective method. These Palmes-type tubes are designed for long-term monitoring, and offer measurement of Sulfur dioxide in the low parts per billion to parts per million range.
Tubes are available for:
- Sulfur dioxide (SO2).
- Simultaneous measurement of Sulfur dioxide and Nitrogen dioxide (SO2/NO2).
Sources of Sulfur dioxide pollution:
- Fossil fuel combustion – industry, power generation, vehicles.
- Domestic boilers or fires.
- Metal extraction.
- Paper production.
- Natural fires.
Potential implications of Sulfur dioxide pollution:
- Harmful to plants – reduced crop yields.
- Involved in acid rain formation – damage to buildings, forests.
- Adverse effects on the respiratory system.
Sulfur dioxide diffusion tubes are designed for passive monitoring of ambient concentrations for 2-4 weeks, giving the user a long-term monitoring option.

Sulfur dioxide is particularly associated with the use of diesel and coal, two widely used fuels. Due to its implications for human health and on the environment, it is widely regulated. Therefore monitoring should be conducted in the following areas at risk of high concentrations:
- Adjacent to fuel burning industries, power stations etc.
- Roadside monitoring as part of traffic management schemes.
- Environmental monitoring – in proximity to volcanoes or in forests to assess potential vegetation damage.
- Indoor air monitoring – buildings near busy roads, in-vehicle concentrations, buildings with open fires.
- Monitoring for health purposes.
- Occupational monitoring (e.g. taxi drivers, bus drivers, machinery operators).
