OVERVIEW
Track motor usage & runtimes with ease
The HOBO Motor On/Off data logger records motor on and off conditions within an AC magnetic field with its internal sensor, or mechanical contact closures from external sensing devices. This logger is ideal for tracking the usage & runtimes of motors, pumps, compressors, and other equipment. The HOBO UX90-004 Motor On/Off Logger is available in a standard 128 KB memory model capable of 84,650 measurements.
Features
- 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
Important Information
Requires HOBOware software and a USB cable. (Note: A USB-A to USB-B mini cable is included w/HOBOware Pro USB Drive software purchase). See compatible items below

SOFTWARE
HOBOware Software
HOBOware software is used for launching, reading out, and plotting data from HOBO® data loggers. With HOBOware, you can also check logger status, filter and export data, save changes to graphs in project files, and scale data with the Linear Scaling and Pulse Scaling data assistants. There are two versions of HOBOware: HOBOware and HOBOware Pro.
