HOBO 3 State/1 Event Data Logger

Discontinued

The HOBO U11 3-State/1-Event Data Logger lets you simultaneously monitor and log state changes in up to three locations plus one time/date-stamped event. The three state and one event channels monitor contact closures or openings driven by external sensors mounted on motors, doors, or other cycling equipment. The HOBO U11 3-State/1-Event Data Logger lets you simultaneously monitor and log state changes in up to three locations plus one time/date-stamped event

Important Information

HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase) and a communications device. See compatible items below.
