Engine recorder ON/OFF UX90-004M

The HOBO Motor On/Off data recorder records the engine running and stopping conditions in a CA magnetic field with its internal sensor or mechanical contact closures from external detection devices. This data recorder is ideal for monitoring the use and duration of engines, pumps, compressors and other equipment. The HOBO UX90-004 engine on/off data recorder is available in a 128-K standard memory model (UX90-004) capable of 84,650 measurements and an extended memory version of 512 KB (UX90-004M) capable of over 346,795 measurements.

Features highlighted

• Both internal motor sensors offer better sensitivity for well protected engines
• External input to measure mechanical contact closures when signal strength is low
• Self-calibration of ON and OFF thresholds ensures reliable readings
• Compatible with HOBOware and HOBOware Pro software for configuration, graphical representation and recorder analysis
• This data recorder works in an indoor environment.
• The UX90-004M data recorder supports the following measures: engine on/off, operating time and open/closed state
