Product introduction:
Sound level meter, also known as (noise meter) is the basic instrument of zui in noise measurement. Sound level meter is generally composed of capacitive microphone, preamplifier, attenuator, amplifier, frequency meter weight network and effective value indicator head. The principle of the ar854-digital sound level meter is that the microphone converts sound into electrical signals, and the preamplifier transforms the impedance so that the microphone matches the attenuator. The amplifier adds the output signal to the weighting network, performs frequency weighting (or external filter) on the signal, and then amplifies the signal to a certain amplitude through attenuator and amplifier. After zui is processed by the digital circuit processor, the corresponding value is displayed on the LCD.
