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. Ideal for monitoring aquifers for saltwater intrusion and road and agricultural runoff, the HOBO U24 Conductivity Data Logger is easy to deploy and maintain. It features a non-contact sensor to minimize drift-related measurement errors, open access to the sensor for cleaning, and software-based drift compensation.
The U24-001 Data Logger is for use in Outdoor and Underwater environments
The U24-001 Data Logger supports the following measurements :
Learn how to collect water quality data with this conductivity and temperature data logger. The HOBO Conductivity U24 Data Loggers is specially coded to provide a non-contact sensor. The electrodes are never in direct contact with water so they do not corrode. In addition, this logger sheds air bubbles for better accuracy measurements. This product also comes with durable housing, providing many years of use in freshwater or saltwater. Moreover, the battery lasts up to three years. Optical communications make it possible for researchers to offload data even when the logger is wet.
