Decibel Data Logger - Records up to 32000 data groups and supports data logging on Windows 10, 8, 7, Vista and XP for easy file management and post-test analysis. - High Accuracy and broad range: measuring range 30 to 130 dB with a stated accuracy of ±1.5 dB; frequency response 31.5 to 8.5 kHz; fast and slow time weighting options; display update rate 2 times per second in FAST and 1 time per second in SLOW. - AC and DC Output: AC signal output 4 Vrms with full bar graph display and an output impedance of approximately 600 ohms; DC signal output 33 mV per dB for direct signal monitoring and data transfer. - Bar Graph Display: LCD shows 3-digit decibel values with auto-ranging bar graph level; includes time and date for context and traceability. Key benefits and use cases - Accurate noise measurement for safety and compliance: ideal for industrial environments, construction sites, and public spaces where SPL monitoring and record-keeping are required. - Data driven analysis: log large data sets to review trends, peak events, and frequency response characteristics over time. - Flexible output options: AC and DC outputs enable integration with external equipment for recording, calibration, or real-time monitoring in various workflows. 2-3 practical applications - Workplace safety and compliance audits: continuously monitor noise levels in factories or workshops, log data for regulatory reporting, and verify exposure levels over shifts. - Audio and sound quality testing: evaluate acoustic environments in studios, theaters, or conference rooms by capturing accurate SPL data across the specified frequency range. - Field environmental noise assessment: study ambient noise around construction sites or urban areas, collect long-term samples, and analyze daily or hourly patterns.
