Product Description:

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 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.
