Hobo U24 Data Logger in action

A few weeks ago, we told you about the new HOBO U24 data loggers. These data loggers are ideal for tracking and monitoring water temperature changes in both salt and freshwater conditions.

Just last week, a colleague pointed them out being used in: Sandwich, Massachusetts by Jo Ann Muramoto (Senior scientist from the Association to Preserve Cape Cod) as part of a Statewide Project to gauge the impact of global warming on river herring.

It's always great to see advances in technology leading to practical experiments and analysis that weren't feasible before.

New HOBO Conductivity and Salinity Data Loggers

We've had great feedback about Onset's new HOBO Conductivity and Salinity Data Loggers


There are two models to choose from for fresh and salt water deployments. Both provide easy access to the sensor for cleaning and shedding air bubbles. HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity.

Fresh Water Option
Hobo Conductivity Data Logger - U24-001

Supported Measurements: Conductivity, Temperature
Ideal for streams, lakes, and other freshwater sources
Non-contact sensor reduces sensor drift
Conductivity range from 0 to 10,000 µS/cm
Easy access to sensor for cleaning

Salt Water Option
HOBO Conductivity Data Logger - U24-002

Supported Measurements: Conductivity, Salinity, Temperature
Ideal for saltwater environments such as bays and estuaries
Conductivity range from 100 to 65,000 µS/cm
Non-contact sensor reduces sensor drift
Easy access to sensor for cleaning
