NOR118-N1 with Electronic Level Recorder

The Electronic Level Recorder function (also known as a Time History) records the A weighted equivalent level (LAeq), the A weighted maximum sound pressure level (LAmax) and the Peak Level (Lpeak, with C or Z weighting), all simultaneously. These values are stored at regular intervals, giving a profile of the noise over time.

The rate that each measurement can be stored at can be set at 1 second or more. For rates below 1 second (down to 100ms) the Advanced Electronic Level Recorder option is needed.

The large memory fitted as standard to the NOR118 means that up to 2,500,000 values can be stored, giving the ability to store detailed information about the noise for long periods of time.
