Hobo UX90 motor, on/off logger is a matchbox-sized, LCD-display data logger for monitoring run-times of motors, pumps, compressors and other equipment. It can record up to 340,000 equipment on/off cycle changes, and uses powerful graphing and analysis software to convert the recorded data into time- and date-stamped graphs. The logger quickly and securely attaches to motor housings via built-in rare earth magnets—without any wiring—eliminating the need for equipment lockouts.
