pHionics - Model STs Series - Dissolved Oxygen Sensor - Specification Sheet

The pHionics STs Series Dissolved Oxygen sensor (or sonde) accurately measures dissolved oxygen (0-20 mg/L or percent saturation) and temperature (0-50°C) over long periods of time with little maintenance required.  These measurements are output via two noise-resistant 4-20 mA signals compatible with most systems. A narrow diameter allows the STs Series to go where other sensors cannot while the durable, chemical-resistant housing ensures many years in-use.  The electrode tip (anode) has a large surface area that improves oxygen exchange consistency across the membrane while reducing the frequency of fouling.hange consistency across the membrane while reducing the frequency of fouling.
