Professional Decibel Meter: The sound decibel meter features a measurement range of 30 to 130 dB, with an accuracy of ±1.5 dB and a resolution of 0.1 dB. Its precision condenser microphone ensures reliable measurements across a frequency range of 30 Hz to 8 kHz, making it ideal for professional sound level monitoring in both home and workplace environments.
A/C Weighting: The SPL meter’s A-weighted mode replicates the human ear's response to low-intensity sounds, making it ideal for measuring environmental noise and ensuring hearing safety. In contrast, the C-weighted mode offers a nearly flat response, capturing low-frequency content to accurately assess high-intensity noise from sources like industrial machinery.
MAX/MIN & Data Hold: The db meter captures maximum and minimum sound pressure levels during monitoring, recording acoustic peaks and valleys. The Data Hold function allows users to freeze any reading on the display for easy reference, enabling them to track the highest and lowest levels over time.
Fast & Slow Time Weighting: The noise meter's FAST response mode (0.125 s time constant) captures rapid changes in noise levels, making it ideal for measuring fluctuating sounds like traffic or intermittent sources. In contrast, the SLOW response mode (1 s time constant) provides a stabilized average, making it suitable for steady-state noise such as that from HVAC systems or constant machinery.
2.25-Inch LCD Screen with Backlight: This decibel meter with data logging features a large LCD screen that clearly displays noise levels in decibels, making it easy to read from a distance. A long press of the backlight button activates the backlight, ensuring visibility even in low-light conditions. It’s ideal for monitoring noise levels at home, in communities, vehicles, workshops, and schools.
Package Includes: You will receive 1 × Decibel Meter, 1 × Storage Box, 6 × AAA Batteries (3 for backup) , 1 × User Manual, 1 × Screwdriver.
