/Low Dual Frequency Measurement Enables simultaneous monitoring of both and low frequency components for accurate noise analysis across the spectrum. A/C Sound Level Frequency Meter Provides sound level measurements with A/C weighting to support safety assessment and regulatory compliance. F/S fast and slow time weighting Offers fast and slow response options to match measurement needs, capturing rapid peaks or longerterm trends. AC and DC analogue signal outputs Delivers continuous analog signals suitable for data logging, remote monitoring, or integration with other equipment. Use scenarios Workplace noise assessment Use in factories, construction sites, and offices to verify regulatory compliance and protect worker hearing by analyzing sound levels with appropriate weighting and response times. Building services and equipment testing Analyze noise from HVAC systems, pumps, and other machinery in commercial or residential buildings to inform design decisions and mitigation strategies. Audio equipment and product testing Evaluate consumer electronics and audio components by monitoring sound levels and response characteristics during development and quality control.
