Available with 8K or 64K memory capacities, the HOBO Pendant loggers can be used for short-term shipping applications or year-long remote deployment. Data readout is fast and easy using HOBOware software (Windows) and the convenient Optic USB Base Station. High and low alarm LEDs provide visible verification that temperatures have been within the desired range throughout deployment (HOBO Pendant temp version only).

Required Software & Communications Hardware

HOBOware Software and an Optic USB Base Station* with Coupler, are required to operate the HOBO Pendant loggers. The Optic USB Base Station includes an Optic Base Station and Pendant Coupler.

Optic USB Base Station and Coupler

The Optic USB Base Station offloads a full 64K logger in 30 seconds. The Base Station connects directly to a USB port on a computer, and the coupler connects the logger to the Base Station. The Optic Base Station is splash resistant.

*The HOBO Waterproof Shuttle can also be used as a base station.
