HOBO U12 Family of Data Loggers

12 Bit Loggers with USB interface

The U12 series of data loggers offers models with internal sensors and / or models with external channel(s) that accept a wide range of sensors / input cables.

HOBO U12 loggers provide 12-bit resolution for detecting greater variability in recorded data, direct USB connectivity for convenient, high-speed data offload, and a 43K measurement capacity. The HOBO U12 family of loggers allows users to affordably monitor temperature, humidity, light intensity, and other measurements required for indoor energy, HVAC/R, and industrial projects.
