Details

The Onset U24-001 HOBO Freshwater Conductivity Data Logger collects water quality data. The HOBO U24-001 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 HOBO U24-001 conductivity data logger features a non-contact sensor with a Titanium Pentoxide coating. This coating prevents the sensor from coming in contact with the water, which in turn prevents tarnishing or corrosion associated with traditional electrode sensors. This sensor coating is also inert, enabling fouling to be easily wiped off the sensor.

Note: U24-001 requires the HOBOware software (free to download) to operate, and either a U-DTW-1 Waterproof Shuttle or the Base-U-4 Optic USB Base Station for configuration and data offload. Please also note that a USB interface cable comes with the purchase of a HOBOware Pro CD (BHW-PRO-CD), only.
