The HOBO U12 data loggers can now measure and record power in the kW realm, dc current, air velocity, gauge pressure, differential pressure, and other energy and environmental parameters. The expanded measurements are made possible through the introduction of a compact power adapter, enabling users to conveniently power external sensors that require 12-Vac excitation power. The adapter can also power any user-supplied external sensor that requires up to 400 mA at 12 Vdc. ONSET COMPUTER CORP., Bourne, MA. (800) 564-4377.
