Digital Sound Level Meter:Is perfect for measuring environmental noise in various settings like factories, workshops, schools, residential areas, and offices. It is also ideal for applications in noise engineering, quality control, and health prevention, ensuring compliance with sound level standards across diverse environments. High Precision: DB Meter Offering a measurement range of 30 to 130 dB with an accuracy of ±1.5 dB at 94 dB and 1 kHz, this meter features a display resolution of 0.1 dB. Such precision makes it suitable for both professional environments and regulatory compliance. Weighted Measurements: Equipped with an weighted filter, the meter automatically adjusts its display range to prioritize frequencies that are most audible to the human ear. This function is essential for accurate environmental noise assessments. Fast/Slow Response Modes: With a simple press of the MODE key, users can toggle between FAST and SLOW response speeds. FAST mode is useful for real-time monitoring of varying noise levels, while SLOW mode provides average readings ideal for stable noise environments. Advanced Features: The noise recorder captures maximum and minimum sound levels, holding data for over 3 seconds with a standard sample rate of 0.5 seconds and a maximum error of ±5%. The HOLD function freezes readings on the display for thorough analysis, and an OVER/UNDER indicator alerts if readings are beyond the measurement range, ensuring all data collected are within operational limits.
