Onset Computer Corp.'s 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. The logger can record up to 340,000 equipment on/off cycle changes, and uses graphing and analysis software to convert the recorded data into time- and date-stamped graphs that can be exported via a Bulk Export tool. The logger attaches to motor housings via built-in rare earth magnets, without any wiring, and its HOBOware software can run on both a Mac and a PC.
