Feature

●High Accuracy: This noise meter ensures the highest level of accuracy with noise levels ranging from 30 to 130dB,guaranteeing accurate readings every time.
●Fast Response: Whether you are monitoring sudden or gradual noise changes,the instrument is ready to meet the demands of a 125 ms fast sampling rate and a 1000 ms slow sampling rate.
●Reliable Detection Mechanism: Equipped with a 1/2-inch condenser microphone,the unit provides stable,reliable and accurate detection,capturing even the tiniest noise decibels so they dont go unnoticed.
●Intuitive Display: The backlit color display not only provides clear readings,but also ensures that users can operate the unit in a variety of different lighting conditions.
●Weighted Mode: The A-weighted and C-weighted mode are designed to mimic the human auditory response,with the A weighting simulating the human ears response to low-intensity noise,while the C weighting captures the characteristics of high-intensity mechanical noise. This ensures that the readings you receive are consistent with human perception.
