Workplace Noise Dosimetry Solutions

Svantek provides two versions of personal noise dosimeters:

Standard SV 104A
Intrinsically safe SV 104BIS for hazardous environments.

The SV 104A is built to IEC 61252 and ANSI S1.25-1991 (R2020) and measures to BS EN ISO 9612, while the SV 104BIS adds ATEX and IECEx certification, delivering durability, safety, and accuracy in one instrument.

Regulations

The Regulations set a lower exposure action value of 80 dB(A), an upper exposure action value of 85 dB(A) and an exposure limit value of 87 dB(A), each with a corresponding C-weighted peak.

Configure your noise dosimeter for any application

Three independent dosimeters run at the same time, each with its own exchange rate and threshold, so one survey can report against more than one criterion without repeating the measurement.

Ensure precise noise monitoring with options such as:

Triggered audio recording or real-time octave band analysis to match your project’s requirements.
Add vibration dosimeters or acoustic calibrators when needed
All devices are powered by Svantek’s common software platform for seamless operation, data management, and reporting.

We’ll help you select the right configuration for full compliance and efficient workflow.

Trusted by experts worldwide

"Octave-band logging and voice notes make ISO 9612 reporting simpler. The data is transparent, defensible and easy to share with customers."

"Small, rugged and worn on the shoulder, workers hardly notice them. Reliable measurements mean fewer repeat surveys."

"The MEMS microphone is virtually indestructible. After years of use, the accuracy remains stable, so there are no costly replacements.”
