A sound intensity meter (decibel meter, sonometer) is a device for recording the sound intensity level of the environment. It enables precise measurement of the noise level, e.g. in industrial plants, in offices, the noise of passing trains, traffic, running fans in computers, etc.
Simple operation, large digits on the display, a number of functions facilitating work and a profiled housing that fits perfectly in the hand make working with this meter easy and pleasant.
Alarm of exceeding the set value: the function allows you to set the volume level above which the backlight of the screen will flash
Max/Min button: freezes the highest/lowest value of the current measurement on the screen
Data hold button: Freezes the current measurement value on the screen
The device automatically turns off after 10 minutes of inactivity. The setting can be deactivated when turning on the device.
