    Data Logger

    Onset’s HOBO Conductivity Logger is a high-accuracy, easy-to-maintain data logger that reduces the cost of measuring conductance and temperature in streams, lakes, and other freshwater sources. The logger is designed with a non-contact sensor, provides open access to the sensor for easy cleaning and software-based drift compensation using calibration points from the start and end of each deployment. Onset’s HOBOware Pro software makes it easy to graph and analyze conductivity data. The logger offloads data to a PC via an optical USB interface.
