YSI ProSample Portable Samplers

YSI’s ProSample portable samplers feature a proprietary peristaltic pump for highly accurate sampling in applications such as surface water, stormwater, and wastewater.

With multiple automated portable samplers to choose from and the ability to sample based on time, analog signal, digital pulse, and/or measurements from an SDI-12 device (ProSample P-12 and ProSample PM-12 models only), the ProSample can be the final piece of your monitoring installation. Composite sampling can be completed with all models, while discrete sampling can be completed with the ProSample P and ProSample P-12.

Available ProSample models include:

  • ProSample P: full-size portable sampler
  • ProSample P-12: full-size portable sampler with SDI-12 connectivity
  • ProSample PM: mini portable sampler
  • ProSample PM-12: mini portable sampler with SDI-12 connectivity

Included with each ProSample:

  • 5 meter suction hose with screw connection and sinker weight
  • 10L PE container (only the ProSample PM and the ProSample PM-12)
  • Battery
  • USB cable
  • Two peristaltic pump tubes
  • Printed copy of the ProSample Getting Started Guide
