Digital Sound Meter, Measure Noise Level for Classroom, Home, Street

Product Description Summary

The noise meter is an environmental sound level instrument that can be used in various settings including factories, workshops, schools, residential areas, offices, traffic roads, and audio environments for sound level measurements. It is also suitable for noise engineering, product quality control, and health prevention and control.

Function Features

• A Weighted network: The noise meter automatically switches between different ranges and displays the appropriate value.
• F/S mode selection: The noise meter offers a fast or slow response speed, which can be selected by pressing the MODE key.
• Maximum (MAX) measurement: By pressing the RANGE key, the noise meter can measure the maximum value (MAX) and minimum value (MIN). The maximum value is recorded for more than 3 seconds with a sampling rate of 0.5 seconds, and the maximum error is ± 5%.
• Measurement result (HOLD) function: The noise meter has a HOLD key that can be pressed to hold the measured sound level value.
• Sound level OVER or UNDER indication: If the display shows "UNDER" or "OVER" characters, it indicates that the sound level is below 30dB or above 130dB.
• LCD with backlight: The noise meter has a backlight display that allows for easy reading even in dark environments. The backlight will automatically turn on after power-on and turn off after 30 seconds. The backlight can also be manually turned on by pressing the backlight button.
• Auto Power Off function: The noise meter will automatically shut down after 3 minutes of inactivity to conserve power.
• Low-battery indicator: When the battery voltage is low, a symbol will appear on the display to indicate that the battery needs to be replaced.
