The Taiwan Berkeley BK8650 Noise Meter is a portable precision sound level measuring instrument, widely used for noise monitoring in various environments. It employs advanced capacitive microphone technology to accurately measure sound pressure levels ranging from 35dB to 90dB on the low range and 75dB to 130dB on the high range. The device features A and C frequency weighting functions, which can simulate the human ear s perception of different frequencies. It also supports slow and fast time weighting, allowing it to adapt to noise variations in different scenarios.

The BK8650 Noise Meter is designed with user-friendliness in mind and can be operated with one hand. Its sturdy anti-shock casing enables it to be used stably in various complex environments, from outdoors to indoors and offices. In addition, it has a maximum value lock function that can record the highest noise value during the measurement process, facilitating data comparison and analysis for users. The device is equipped with AC and DC output functions, allowing it to be connected to other devices for further data processing.
