HOBO Conductivity Data Logger

This high-accuracy conductivity data logger is a cost-effective way to collect water quality data. The HOBO U24 measures and records both 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. This product’s open access to its sensor simplifies cleaning and maintenance. The HOBO U24’s non-contact sensor minimizes measurement errors related to drift. In addition, the logger features 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:

Temperature • Conductivity/Salinity

HOBO U24-001.  0 – 10 000 µS/cm

HOBO U24-002-C.  100 – 55 000 µS/cm
