// Noise Dosimeters

SV104A

The SV  104A is a personal noise dosimeter with a Bluetooth® communication supported by the Smartphone application called Assistant. For measurements of noise at work in accordance to ISO 9612 as well as OSHA, MSHA and ACGIH. The dosimeter has a very robust MEMS microphone that has a lifetime warranty. We have designed the SV  104A to make noise dosimetry measurements easier. Firstly, the voice comment feature replaces necessity of identifying the dosimeter with a different type of stickers. Secondly, a single large measurement range of 53 dB to 141 dB enables measurement in all kinds of working environment. But mostly, the auto-calibration is what makes the SV  104A easy in use.
