HOBO water quality monitoring solutions include loggers for measuring conductivity, salinity, pH, dissolved oxygen, and more – in lakes, streams, rivers, estuaries, and coastal waters.
HOBO Loggers are built to last and withstand a wide range of environmental conditions including temperature extremes, rushing rocky streams and ocean storms. Award-winning HOBO water monitoring data loggers provide years of reliable, accurate performance.
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 MX2202 water temperature/light level logger leverages the power of Bluetooth Low Energy (BLE) to deliver accurate temperature and relative light-level measurements straight to your iOS or Android mobile device.
A miniature, waterproof two-channel temperature and relative light level data logger, this 8K model is value-priced for deployment in indoor, outdoor, and underwater applications measuring relative light levels and ambient temperatures.
A miniature two-channel temperature and relative light level data logger, this 64K model is waterproof and value-priced for deployment in indoor, outdoor, and underwater applications measuring relative light levels and ambient temperatures.
The pHionics STs Series™ pH sensor/transmitter provides highly accurate pH measurement from 0-14 pH. The electrode is glass with a silver/silver chloride reference wire and double junctions to ensure long-term stability in harsh chemical solutions.
