This personal dosimeter has a robust 1/2 MEMS microphone enabling easy calibration using most commonly available acoustic calibrators. The SV 104 is a cable-free dosimeter and is typically attached to the user’s shoulder, close to the ear using the mounting clips supplied.

The measurement data is safely stored in the large 8 GB memory and the amazing OLED screen displays information in both text and graphical form and offers excellent visibility even in full daylight.

The instrument works with Svantek’s specialist health and safety software package, Supervisor and is powered using built-in rechargeable batteries or through the USB interface which also enables easy connection between the SV 104 and a PC.

Never before has a noise dosimeter been so accomplished yet affordable, making your measurements more accurate and reliable than ever before.

What is a noise dosimeter?

A noise dosimeter is a sound measuring instrument meeting IEC 61252 international standard’s performance criteria in the range of 55 dB to 140 dB and frequencies from 20 Hz to 8 kHz. Usually, noise dosimeters follow the same requirements as class 2 sound level meters.
