Digital Decibel Meter

A decibel meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, a sound level meter uses a microphone to capture sound. The sound is then evaluated within the device and acoustic measurement values are displayed.

Features & Benefits :
  • Accurate Measurement - The decibel meter provides accurate and reliable measurements of sound levels, range 30-130dB, accuracy +-1.5dB, it helping you to maintain a safe and healthy environment by ensuring noise levels are within acceptable limits.
  • A-Weighted - The db meter uses A-weighting, which is the most common weighting scale used in measuring sound levels. This ensures that the readings are adjusted to mimic the human ear's response to different frequencies, providing more accurate results.
  • Capacitive Microphone Sensor - Our dB noise meter is equipped with a high-quality capacitive microphone sensor that captures sound waves and converts them into electrical signals, ensuring precise and reliable measurements.
