NSA 181K - cooled - The sampler for all campaigns

Key benefits

  • Compact instrument build up in modular structure, insulated PVC housing
  • Large collection funnel to catch the precipitation (approx. 500cm²)
  • Bottle configurations from 2x 10l to 16 x 0,25l available
  • Chemically neutral material of single components: HD-PE/Silicone alt. PTFE/DURAN-glass (optional to be chosen with order)
  • Automatic climate control system for sample room to 4-6°C (adjustable temperature 3…10°C optional) - Cooling FCKW free
  • Various options allowing customizing to most applications


The precipitation sampler is used for the purpose of collecting the precipitation, depending of its configuration, in a large sample bottle, in 8 separate day or single samples or weekly samples. The individual sample bottle can be easily removed from the apparatus at the end of the period of measurement for laboratory analysis. Every single component which is used for measurement is made out of chemically neutral material and placed in a thermically insulated housing. At high temperatures the housing is cooled automatically to avoid overheating from intense radiation of the sun. For winter operation an electronically controlled funnel heating and a heating for the sample bottles, respectively sample room heating are provided.
Direct material, funnel shape and the collection surface correspond to the standards of the VDI-recommendations 3870. (VDI: Association of German Engineers)
