Remote Water Quality Monitoring Systems

The new low-cost HOBO® MX2501 pH and Temperature logger is designed for long-term monitoring of pH in estuaries, lakes, streams, rivers, and oceans.

The HOBO U24 Conductivity Logger is a high-accuracy, cost-effective water quality data logger for measuring conductivity and temperature in streams, lakes, and other freshwater sources

The HOBO U24-002-C is a cost-effective data logger for measuring salinity, conductivity and temperature in saltwater environments with relatively small changes in salinity (±5,000 μS/cm) such as saltwater bays, or to detect salinity events such as upwelling, rainstorm, and discharge events.

The HOBO U26 Dissolved Oxygen Logger is a highly precise, low-cost data logger for measuring concentrations of oxygen in lakes, streams, rivers, estuaries, and coastal waters. Used by aquatic biologists, hydrologists, and other research professionals, the HOBO U26 combines the high accuracy, robust performance of industry-leading RDO® Basic (Rugged Dissolved Oxygen) sensor technology with an easy-to-maintain design.

The HOBO RX3000 is Onset’s next-generation remote data logging station that provides instant access to site-specific environmental data anywhere, anytime via the internet.

The pHionics STs Series™ pH sensor provides accurate pH and temperature measurements from 0-14pH to a datalogger or RTU for continuous water quality monitoring.

The pHionics STs Series™ Dissolved Oxygen sensor 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.

The pHionics STs Series™ ORP sensor provides reliable ORP (redox) and temperature measurements to a datalogger, RTU, PLC, or SCADA system for continuous water quality monitoring.

The pHionics STs Series™ Conductivity is a water quality sensor designed to pair with a datalogger or RTU for real-time data capture.
