These high-precision conductivity data loggers are a cost-effective way to collect water quality data. The HOBO U24-001 data logger records both conductivity and temperature measurements in streams, lakes and other freshwater sources. This data logger is recommended for monitoring aquifers for saltwater intrusion and runoff from roads or agricultural land.
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 for detecting salinity events such as surges, storms or discharges. It can also be used to collect salinity data for salinity compensation of HOBO U26 dissolved oxygen data.
This open-to-its-sensor product simplifies cleaning and maintenance. The non-contact HOBO sensor minimizes measurement errors related to changes. In addition, the data loggers feature software-based shift compensation.
It works in outdoor and underwater environments.
Supports conductivity/salinity and temperature.
Note: When monitoring salinity in waters with more than +/- 5,000 µS/cm variation, refer to the accuracy shown in Plot C in the product specifications to determine if the accuracy is acceptable for your needs. Monthly field calibration readings are generally required to achieve the best accuracy.
