pHionics 0-1,000 µS/cm Conductivity & Temperature Sensor

The pHionics STs Series™ Conductivity water quality sensor is compatible with HOBO RX stations to capture real-time conductivity and temperature data.  These measurements are output via two 4-20mA signals that easily connect to HOBO stations and HOBOnet motes with analog inputs. A narrow diameter allows the STs Series to go places others can’t, while the chemical-resistant housing ensures the sensor endures for many years.  Proprietary electrode technology provides stable measurements to reduce calibration frequency.   All parts, including the cable, are easily replaceable without tools In addition, isolation, differential amplification, and shielding ensureaccurate and low-noise measurements, all while remaining low-power.These features make this conductivity sensor well-suited for applications such as groundwater monitoring, wastewater treatment, aquaculture, pollution monitoring, etc.Noise Reduction Technology
