fex0912ts22_inbody.jpgThe Onset HOBO UX90 motor on/off logger monitors run times of motors, pumps, compressors and other equipment. Recording up to 340,000 equipment on/off cycle changes, the matchbox-sized, LCD-display data logger uses graphing and analysis software to convert the recorded data into time- and date-stamped graphs. It attaches to motor housings via built-in rare earth magnets, without any wiring. The logger can be used in a range of building performance monitoring applications, including HVAC/R systems diagnostics, compressed air systems monitoring and general troubleshooting of motors, pumps and fans.
