Accurate Measurement - The decibel meter provides accurate and reliable sound level measurements, with a range of 30-130dB and an accuracy of ±1.5dB, helping maintain a safe and healthy environment by ensuring noise levels remain within acceptable limits.

A-Weighted - The decibel meter uses A-weighting, the most common weighting scale used in measuring sound levels. This ensures that measurements are adjusted to mimic the human ear's response to different frequencies, providing more accurate results.

Conductive Microphone Sensor - The Noyafa decibel meter features a high-quality conductive microphone sensor that captures sound waves and converts them into electrical signals, ensuring accurate and reliable measurements.

HD Backlit Display - The decibel meter features a high-definition backlit display, which improves visibility in low-light conditions, making it ideal for use in various settings, including classrooms and homes, where lighting may be limited. The data hold function allows pausing the current noise measurement display, effectively "freezing" the data.

Certification - It passes RoHS, FCC, and CE compliance checks, and Noyafa is ISO 9001 certified.
