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.

Features:

Non-contact sensor reduces sensor drift for easy maintenance
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
