O2, pH, & CO2 Optical Process Monitors

Designed to operate with Polestar's oxygen, pH, and CO2 sensors, the DSP Series Monitors are the core of any Polestar process monitoring system. The DSP Series transmitters include automatic temperature and pressure compensation as will as a proprietary AGC (automatic gain control) to optimize readings and maximize sensor lifespan.


The NEMA 12/4X IP 65 enclosure has water-tight cordgrips for brining in process temperature and pressure data via 4-20 mA signals, a simple and intuitive menu, and a high visibility VFD display. The system also offers 4-20 mA isolated loop analog outputs. If desired, process temperature can be monitored using on-board circuitry for PT100 RTDs.


By virtue of its rugged design and reliable, long-term measurement performance, Polestar's DSP Optical Process Monitors are suitable for use in a range of environments, including laboratories, pilot and production plants, as well as outdoors. Applications enabled by the robust, non-electrode design include bioprocessing, food and beverage, high purity water, fuels and biofuels, and environmental monitoring.
