NSA 181 - basic - The sampler for inorganic content

Key benefits

  • Climate control system light for sample room with heating and ventilation system
  • Contact material (silicone and HD-PE) is ideal for collection on acidifying components and inorganic content. (For others, please check the optional items.)
  • Rugged instrument for year-round operation in most climate conditions
  • Manifold options allow the adaptation to the most applications.
  • Proven technology for drive and rain detection allowing reliable separation from wet content to dry contents


Precipitation contains a high amount of organic, inorganic and suspended substances. It is believed to be the major atmospheric purification process and has a high contribution to the trace element cycle in the atmosphere.
The Precipitation Sampler NSA181 is equipped with a cover lid for a wet only application. This lid is opened only during deposition. So now it is possible to catch the wet precipitation only. This characteristic is in contrast to bulk samplers, which collect both the wet deposition and the dry deposits (e.g. dust).  
The equipment guarantees automatic all year operation, possible through the use of heating at temperatures of 0°C and below and ventilation at temperatures of 25°C and more in the sample room.
Various sample inserts of bottle from 0,25 to 10 liters allow a good adaptation to the users sample procedures and collection intervals. And multiple choices of options allow fitting the precipitation sampler to the application.
