Produktbeschreibung

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 HOBO U24 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.

Non-contact sensor provides long life and less measurement drift
Provides easy access to 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
USB optical interface provides high-speed, reliable data offload in wet environments
Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport
