Hobo Pendant Data Logger
Compact, lightweight & waterproof, temperature/light intensity (illuminance) logger.
The HOBO pendant data logger is a waterproof, ultra-compact, and inexpensive data logger. There are two types: a 1-channel temperature type and a 2-channel temperature/light intensity type. Logger settings and data retrieval are done optically via an Optic USB base station. These operations can be easily and quickly performed using the dedicated software HOBOware. Additionally, the 1-channel temperature type is equipped with an alarm function using LED lights, allowing users to quickly determine whether the measured subject is within the expected temperature range.
