Features:

  • Weather-proof housing and roof made of durable stainless steel; upper panel door included
  • Three separate technical compartments in the upper section of the sampler to protect the pump, electronics and refrigeration unit
  • Freely adjustable and highly accurate temperature control for the sample storage chamber, for ambient temperatures from -25°C to +42°C
  • High-performance vacuum sampling system – alternatively available with any other WaterSam sampling system
  • Borosilicate glass metering vessel protected in sample storage chamber to minimize sample falsication that could stem from temperature extremes
  • Hose inlet on the left and right side; optionally from below
  • Available with XY Distributor for direct filling of numerous bottle sets without cross-contamination
  • Simple upgrade to monitoring station can be made at anytime
  • Wide range of optional equipment: housing materials, pumps, valves, etc.

Direct Bottle Filling with Numerous Possibilities

WaterSam XY Distributor system has been in use successfully for nearly 20 years and with its wide array of possibilities, reliable operation and minimal follow-up costs have made it the distributor of choice among our customers. The two-axis system makes full use of the entire sample storage chamber by using coordinates to travel and locate bottle positions.
