• Waterproof to 225 feet (70 m)
• Long-life battery offers extended monitoring

Measure and record conductivity and temperature in underwater environments with HOBO Conductivity Data Loggers. Loggers feature a non-contacting sensor for long life and minimal measurement drift. The sensor sheds air bubbles for greater accuracy, and is easy to access for cleaning. Loggers are equipped with an optic USB interface that allows for data offload in the field, even when the logger is wet. With a long-life lithium battery and operating range as low as 28°F, these loggers withstand extended deployment in rough conditions.

The HOBO Conductivity Data Logger provides accurate conductivity data in freshwater environments. It's ideal for applications such as environmental impact monitoring, stormwater management, water quality studies and agricultural runoff.

Note: Loggers require either a base station (stock # 10048) or shuttle (choose from stock # 19611 or 10049) for data transfer. They also require HOBOware Pro Software (stock # 10045) for data analysis and logger setup.

Includes: lithium battery and protective cap for communications window.
