A low cost conductivity and temperature datalogger
Now available in both freshwater and saltwater versions, the HOBO U24 Conductivity Logger is a high-accuracy, cost-effective data logger for measuring conductivity and temperature in streams, lakes, and estuaries. Ideal for monitoring aquifers for saltwater intrusion and road and agricultural runoff, the U24 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. HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity.
