YSI ProSample Automated Sampler

ProSample for COVID RNA Testing

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

  • Features
  • Specifications

With multiple 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.

ProSample for use in COVID RNA Testing

YSI’s ProSample portable samplers feature a proprietary peristaltic pump for highly accurate wastewater sample collection which can then be taken to a laboratory for COVID RNA testing.

Samples are collected from the wastewater network in the morning and evening during peak hours. The ProSample units are located adjacent to individual buildings such as apartment complexes whereby sample collection from the wastewater network is representative of the community inside the complex. Once samples are collected they are taken to the laboratory for sample analysis and detection of COVID RNA.

Conducting this efficient sampling solution at a sewer node allows for the connection of COVID to an individual building. Alternatively, testing can eliminate a single building for the presence of COVID and direct efforts elsewhere.  Contact us for more information. | Download our ProSample COVID RNA Flyer
