The HOBO Pro v2 logger's environmentally rugged case is designed for years of reliable use
in outdoor applications. It has enough memory to record over 42,000 12-bit measurements.
The logger uses an optical USB communications interface (via a compatible shuttle or base
station) for launching and reading out the logger. The optical interface allows the logger to
be offloaded without compromising the electronics. The USB compatibility allows for easy
setup and fast downloads.
