Product Description

HOBO Pendant loggers are miniature, water resistant, low-cost units measuring temperature and light intensity for use in a wide range of applications including environmental, underwater and product monitoring.

With 64K memory capacity, this Pendant logger can be used for short term transport monitoring or year-long deployment. 

There are two ways to launch the data logger and offload the data:

  • Using an Optic Base Station with USB interface, and free HOBOware (Windows/Mac) software.

  • Via a Shuttle and HOBOware Pro software. The advantage of this method is that you can launch and offload multiple pendants using the shuttle without the need to take your laptop/PC to each pendant. This is particularly useful for field research.

IMPORTANT: This HOBO data logger needs an Optic Base Station with HOBOware software (FREE), or a Shuttle with HOBOware Pro software. These are available separately.
