Product Description

The simplest and most reliable way to monitor your sites for compliance for both Noise and Vibration legislation. Available in Simultaneous (Vibration and Noise Type 1 Leqs) or Vibration/Noise Only.
The CM3 Model is available in
  • Noise
  • Vibration
  • Simultaneous Noise and Vibration
CM3 Vibration and/or Noise Analyser Features:
  • User-friendly PC software for data analysis to BS6472, BS4142, DIN 4150 and USHM/OSMRE standards
  • Graphics display to view previous results
  • Modem option with SMS text alerts
  • Remote operation and data collection
  • Alarm option with audio/visual warning
  • Unlimited cable lengths and extended battery life via external battery socket [multiple blast event storage in memory]
  • 3 event timer providing automatic unattended monitoring
  • Up to 7 channels
  • With the ability to log in to the CM3 device it allows you a wide range of new features, Under configuration, you now have the ability to remotely change settings on the CM3 such as:
  • Name of unit
  • Enabling your alarms
  • Event Times
  • Input which noise percentiles you need to record (up to 6),
  • Table time interval,
  • Alarm thresholds.
The great news is that you can select all the event parameters from this web page and even change the Leq measurements times on recorded data. For example, say you select 5 minute tables and L10, L90. Clicking table or event data will give you the results over the period selected for these Leq’s. Then, if you change the Leq periods (say a table of 1 hour and L1,L10,L30,L50 and L90), and reselect the event data or table data, the same period of data will now show the new selected Leq values. This gives you the option to ‘change your mind’ after the monitoring has been recorded.

Automatic Trigger Impulse Mode:-
  • Triggers on any vibration exceeding the user defined trigger value.
  • Used for blast monitoring or similar events. Event length user selectable
Continuous Mode:-
  • Used to record Peak Vibration and Sound Leq (in dB(A) or (C)) over extended periods. Manual or automatic operation using 3 event timer, repeated daily.
