Svantek 104 Single Channel Personal Noise Dosimeter
SV 104 Noise Dosimeter brings incredible functionality into a compact style instrument. The SV 104
instrument is a revolutionary new approach to occupational health and safety noise monitoring
offering voice comments and audio events recording functions which are a new concept in an
instrument of this size. 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.
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 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.
