The PolarityChanger enables the SmartSampler2 to drive a peristaltic pump in both flow directions by electronically reversing the polarity of the connected output.
It is ideal for applications requiring controlled intake and discharge using a single pump.

Key Features
- Bidirectional Pump Control
Allows forward and reverse operation of peristaltic pumps without additional wiring effort. - Compact & Rigid Design
Robust housing ensures durability during transport and repeated field deployments. - Weatherproof Housing
Designed for reliable use in outdoor environments, resistant to rain, splash water, and dust. - Bayonet Quick Connect
Secure, tool-free connection to field cables for fast setup. - High Corrosion Resistance
Suitable for long-term deployments in harsh environmental conditions. - Custom Cable Length
Available with cable lengths tailored to individual application requirements.
Typical Use Case
The PolarityChanger is used when a single peristaltic pump must alternately fill and empty a chamber, reservoir, or tubing line.
By connecting through the PolarityChanger, the SmartSampler2 output can reverse pump direction on demand, eliminating the need for multiple pumps.
Note
The PolarityChanger is plug-and-play with the SmartSampler2, requiring no additional licenses.
