The Ermenrich Seek DS20 is a multifunctional device that allows you to measure noise level, humidity and temperature both indoors and outdoors. It can be used to monitor the conditions of residential, office or industrial premises, thereby also checking compliance with standards.

The sound level meter measures the noise level quickly and accurately in the range of 30-130 dB. In addition, the device can determine the air temperature in the range between -20 °C and 60 °C, and the humidity in the range between 0% and 99.9%. It has separate functions for freezing data and storing limit values.

The device can be operated with 3 AAA batteries (sold separately). In order to save energy, the sound level meter switches off automatically after 10 minutes of inactivity. You can disable this feature if needed. It not only displays the measured data on the screen, but also indicates the low battery level.
