4-20 mA Water Quality Sensors

For Environmental Monitoring and Process Control

Simplify your measurements with durable, accurate, and user-friendly water quality sensors.

All sensors are fully submersible, electrically isolated, and designed to last 10+ years. These sensor are designed to be compatible to all 4 - 20 mA compatible monitoirng systems such as SCADA, PLS, and Most Data Loggers and Process Control  

STs Series Conductivity Sensor for process, wastewater and environmental monitoring

The pHionics STs Series™ Conductivity is a water quality sensor (sonde) designed to pair with a datalogger or RTU for real-time data capture.  A narrow diameter allows the STs Series to go places others can’t while the chemical-resistant housing ensures the sensor can stay there for many years.  Proprietary electrode technology provides stable measurements to reduce calibration frequency.   

The pHionics STs Series™ ORP sensor (sonde) provides reliable ORP and measurements to monitor bacterial activity, sanitization, or heavy metal pollution.  This sensor may be connected to a datalogger, RTU, PLC, or SCADA system for continuous water quality monitoring. 

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.

D-phi Series for industrial applications and STs Series for environmental applications

Recommended for process control, wastewater, aquaculture, hydroponics, environmental remediation, and other applications requiring extremely stable, user-friendly, and low-maintenance pH monitoring.
