AS-250 SpectralMon

The AS-250 SpectralMon provides advanced real-time monitoring and analysis with a powerful set of alarming criteria to detect changes in the dynamic signature of your critical machinery or process.

Once a dynamic event is detected, the system instantly informs the control system or other external devices and acts as a digital recorder by capturing important data before and after the event. This information can be used to alert the operator to change process settings or schedule maintenance.
