The HOBO® U24-001 Freshwater Conductivity Logger provides highly accurate water quality data. It measures and records conductivity and temperatures in streams, lakes and other freshwater sources. This logger is recommended for monitoring aquifers for saltwater intrusion and road and agricultural runoff.
The HOBO® U24-001 Freshwater Conductivity Logger provides highly accurate water quality data. It measures and records conductivity and temperatures in streams, lakes and other freshwater sources. This logger is recommended for monitoring aquifers for saltwater intrusion and road and agricultural runoff. The non-contact HOBO® U24 sensor minimises measurement errors due to drift. And the logger features software-based drift compensation. It has a waterproof coating to effectively protect the sensor and can be easily deployed to monitor water purity and pollutant impact.
Benefits:
- Non-contact sensor for long life and minimisation of measurement errors due to drift
- Easy access to the sensor for cleaning and air bubble removal
- Compatible with the HOBO® U24-001 shuttle for easy and reliable data retrieval and transport
- HOBOware Pro software allows calibration of start and end points to enable conversion to specific conductance and salinity
