Frequently Asked Questions

  • How long can the Nor145 monitor unattended?
    With external power supply and NorCloud connectivity, the Nor145 can monitor continuously and indefinitely with automatic data upload. On battery power alone, the instrument provides over 10 hours of operation. For extended deployments, the Nor1545 outdoor monitoring terminal provides weatherproof housing and permanent power.
  • Can weather data be recorded alongside noise measurements?
    Yes, the Nor145 can integrate with external weather stations and include meteorological data (wind speed, direction, temperature, rainfall) in measurements. Weather-triggered pausing can automatically exclude measurements taken during high wind conditions from regulatory assessments.
  • Does the Nor145 meet Saudi PME noise monitoring requirements?
    Yes, the Nor145 is a Class 1 instrument compliant with IEC 61672-1 and provides all the measurement parameters, logging capabilities, and documentation features required by Saudi PME environmental noise regulations and General Environmental Regulations and Rules for Implementation.
