SV 104 New noise dosimeter

sv104

The SV 104 is our latest and smallest ever noise dosimeter. It has incredible functionality, taking full noise dosimeter capabilities into a compact style instrument that beats anything else on the market hands down!
Any instrument is only as strong as its weakest point and on a noise dosimeter that’s  normally  the  microphone.  On  the  SV 104  we’ve  removed  that  ‘Achilles heel‘  by  using  a  revolutionary and virtually  indestructible MEMS microphone.  Add to that an inbuilt tri-axial accelerometer for vibration shock detection and
the SV 104 is firmly placed as both the most technically advanced and the most robust personal dosimeter out there. The SV 104 also uses a class beating high resolution, colour OLED screen which makes taking noise measurement a real pleasure.
Never before has a noise dosimeter been so accomplished yet affordable, making your measurements more accurate and reliable than ever before.
