As a third generation Eigenbrodt GmbH & Co. KG, with a team of qualified co-workers, incorporates the flexibility and the "know how" also to provide solutions for requirements going beyond regular measurement applications. With special consideration to the climatic extremes of the customers measurement site. Main focus is to be found in development in close cooperation with Universities, Scientific Institutions, Weather Services and Environmental Departments, followed by production itself and the marketing of meteorological instruments and environmental measurement products. Our sensors and instruments are working in many national- and international measurement networks such as German Weather Service, Alfred-Wegener-Institute, Met Office, EMEP, GAW, GMOS. Cooperation’s with partner companies worldwide, in many countries offer a customer-friendly service to our users.

    Climatised precipitation sampler for mercury


  • Suitable for GMOS specifications
  • Suitable for DIN EN 15853 For collecting mercury in precipitation
  • Integrated cooling and heating capacity and insulated housing
  • Easy to service
  • Funnel 100 alt. 125mm (to be chosen with order) allowing bottle capacity of 254mm precipitation (@ 100mm funnel)
  • Contact material PTFE and borosilicate glass


    The precipitation sampler is used for the purpose of collecting the precipitation into a large single sample bottle. 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 thermally insulated housing. At high temperatures the housing is cooled automatically (optional) to avoid overheating from intense radiation of the sun. For winter operation an electronically controlled funnel heating and a heating for the sample room are provided.


  • Double walled insulated PVC housing
  • Collection funnel out of borosilicate-glass diameter 100mm alt. 125mm
  • Control electronics for drive for lid
  • Heating for funnel
  • Thermoelectric heating/cooling system for sample bottles
  • Precipitation Sensor RS 85
  • Sample bottle out of borosilicate-glass (others on request)OPTIONS AVAILABLE
  • Sample bottle out of glass or PETG
  • Collection funnel diameter 100mm or 125mm
  • Opto-electronical Precipitation Sensor IRSS 88
  • Precipitation Sensor NRS 80 or RS 85 OP for areas without snow
  • Dry sample container out of PE or DURAN-glass
  • LCD-hour meter
  • Data logging systems
  • Stand base, made of galvanized steel


    For collecting organic content as well as mercury


  • Ideal contact materials for organic and mercury content collection.
  • Various configurations choices allowing very good adaptation to different collection applications.


    Collection of precipitation for analysing organic components as well a mercury in the precipitation, the choice of the best fitting contact material like sample bottles and funnels is very important. In these cases PTFE and DURAN-glass are preferable to HD-polyethylene. For all types of instruments funnels and sample bottles are available in DURAN-glass. The separating system components for type “D”, “T” and “S” are made out of PTFE.


  • bottles out of DURAN-glass
  • hoses in contact with the sample out of PTFE
  • distributor elements being in contact with the sample out of PTFE OPTIONS AVAILABLE
  • Configuration “E-DURAN”: Single sample bottle 5 liters, alt. 10 liters
  • Configuration “D-DURAN”: 2x sample bottle 5 liters
  • Configuration “T-DURAN”: 3x sample bottle 5 liters
  • Configuration “S-DURAN”: 9x sample bottle 1 liters
  • Configuration “S16-DURAN”: 9x sample bottle 0,25 liters

  • Fog Sensor ONED 250(OFS)


  • Reliable fog-sensor
  • Low power consumption
  • detection limit 5000m visibility


    ONES 250 (OFS) is a sensor for visibility with a good cost-performance ration with a main application in traffic purposes. Using so called backscatter technique it measures the amount of water particles i.e. fog in the air that limit the visibility.

    The design allows the operation in various locations and applications. The validity and the stability has been - so far - resulting in satisfied customers.
