Description
The Svantek 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.
Highlights
- Certified for explosive environments, compliant with ATEX and IECEx for use in hazardous zones.
- Patented MEMS microphone with life-time warranty and integrated auto-calibration (TEDS).
- Real-time Bluetooth® preview, allowing remote data access and alarms via smartphone app.
- Simultaneous octave and audio recording (options), enabling noise source identification and hearing protector selection.
- Built-in vibration sensor, detecting misuse and ensuring result integrity.
- 45-hour runtime, supported by fast USB charging and docking station options.
Features
Intrinsic Safety for Hazardous Environments
Certified noise monitoring designed for explosive atmospheres
SV 104BIS is an intrinsically safe personal noise dosimeter, designed for use in explosive-risk environments such as mines, refineries, and chemical plants. Certified under ATEX and IECEx, the device meets international standards for intrinsic safety by limiting electrical and thermal energy to prevent ignition.
MEMS microphone with lifetime warranty
Rugged design for reliable, long-term performance
SV 104BIS uses a patented MEMS microphone designed for tough industrial environments. Its solid-state build ensures shock resistance, low power use, and stable sensitivity. Backed by a lifetime warranty, it delivers accurate, maintenance-free noise measurements for years.
Noise source recognition
Real-time analysis and audio logging for better insight
The SV 104BIS offers optional 1/1 or 1/3 octave band analysis and simultaneous audio recording, enabling detailed identification of noise sources. This dual approach supports accurate selection of hearing protectors and provides context for critical noise events during post-analysis.
Mobile app support
Remote access, live preview, and limit alerts via Bluetooth®
The SV 104BIS connects via Bluetooth® to the Assistant mobile app, allowing users to preview real-time noise levels, control measurement sessions, and receive alerts when noise limits are exceeded—all without interrupting the worker.
Standards compliance and accuracy
Full alignment with Class 2 and occupational noise standards
The SV 104BIS meets ANSI S1.25, IEC 61252, and IEC 61672 Class 2 requirements, ensuring high accuracy in industrial noise measurements. It supports ISO 9612, OSHA, MSHA, and ACGIH methodologies, recording Leq, Max, Min, Peak values alongside DOSE, TWA, and Lav with dual time-history logging for detailed exposure analysis.
Auto-calibration feature
Accurate, user-independent setup with built-in calibration memory
The SV 104BIS features an auto-calibration system enabled by a TEDS-equipped MEMS microphone, which stores calibration data directly in the microphone. This eliminates manual setup errors, ensures traceable accuracy, and streamlines field use by automatically recognizing calibration parameters during setup.
Applications
Occupational Noise
Compliant measurements across all workplace standards
The SV 104BIS supports noise exposure monitoring in accordance with ISO 9612, OSHA, MSHA, ACGIH, and the EU Noise Directive. Its wide 100 dB dynamic range (from 53 dBA Leq to 143 dB Peak) ensures accurate assessment in diverse industrial environments, from low-level exposure to extreme noise events.
