Harmony NM73 Environmental Noise Monitoring System An Automatic environmental noise monitoring system is consist
of automatic noise measuring instrument, transmission equipment, computer and operating software.
The system provides the information of a noise level, location, device status
and provides the accurate noise data for the establishment
of an environmental noise related policies.

    MN 7301 : Moving type Noise and Vibration Measurement System.
MN 7302 : Fixed type Noise and Vibration Measurement System.
   MN 7303 : Vehicle type Noise and Vibration Measurement System.
        MN 7304 : Multi-purpose Noise and Vibration Measurement System.
Features - Provide an real-time noise data over the internet automatically.
- Statistical processing of the noise level automatically about a daily, weekly, monthly, annual data.
- Installation is non-limited because it can be to connect as an wireless or wired internet.
- Using a weatherproof external microphone is not affected by changes in the climate
    and environment
