Hobo UX90-004 Motor On/Off Data Logger

SKU: UX90-004

The HOBO Motor On/Off data loggerrecords motor on and off conditions within an AC magnetic field with its internal sensor, or mechanical contact closures from external sensing devices. This data logger is ideal for tracking the usage and runtimes of motors, pumps, compressors, and other equipment. The HOBO UX90-004 Motor On/Off Data Logger is available in a standard 128 KB memory model (UX90-004) capable of 84,650 measurements and an expanded 512KB memory version (UX90-004M) capable of over 346,795 measurements.

Highlight:

Dual internal motor sensors gives better sensitivity for well-shielded motors
External input for measuring mechanical contact closures when signal strength is low
Auto-calibration of ON and OFF thresholds ensures reliable readings
Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis
