SV 104 BIS is a Class 2 personal noise dosimeter certified for use in explosive atmospheres. It combines a robust MEMS microphone with intrinsic safety in accordance with ATEX and IECEx, making it ideal for monitoring worker noise exposure in hazardous industrial environments. The dosimeter measures noise levels from 53 dBA Leq to 143 dBA Peak, logs data with high resolution, and records 1/1 or 1/3 octave bands and audio events for detailed post-analysis.
Bluetooth® connectivity enables real-time data preview on mobile devices using the Assistant app, while the built-in triaxial vibration sensor ensures traceable and accurate results, even during movement or misuse. With a life-time warranty on the microphone and up to 45 hours of operation on a single charge, the SV 104 BIS offers long-term reliability and performance for noise exposure assessments aligned with ISO 9612, OSHA, MSHA, and ACGIH standards.
