Intrinsically safe noise dosimeter SV 104BIS

5.0 (20 Reviews)
The SV 104 BIS is a Class 2 personal noise dosimeter designed for safe and precise noise monitoring in explosive-risk environments. Certified under ATEX and IECEx standards, it integrates intrinsic safety with a rugged MEMS microphone, ensuring durability and accuracy in demanding industrial conditions. The device measures noise levels from 53 dBA Leq to 143 dBA Peak, supporting 1/1 and 1/3 octave band analysis and audio event recording for comprehensive post-measurement evaluation. Built-in Bluetooth® connectivity allows real-time... monitoring and data access via the Assistant mobile app, while the triaxial vibration sensor detects motion or handling errors, maintaining data integrity and traceability. With up to 45 hours of battery life, a lifetime MEMS microphone warranty, and compliance with ISO 9612, OSHA 29 CFR 1910.95, MSHA, and ACGIH standards, the SV 104 BIS delivers unmatched reliability and precision for occupational noise assessments in hazardous work zones.

The SV 104 BIS is a new version of an intrinsically safe noise dosimeter with a robust 1/2” patented MEMS microphone. The new microphone has a large dynamic range, auto-calibration feature and TEDS memory that stores the calibration info in the microphone itself. The SV 104 BIS Bluetooth® interface enables current results to be previewed on a smartphone or tablet using our Assistant application.

The smartphone application also signals an alarm when the set noise limits are exceeded.

FAQ Component

Frequently asked questions

What is a noise dosimeter?

A noise dosimeter is a small device worn near the ear that measures how much noise a person is exposed to during a work shift.

Why should I use a noise dosimeter?

It automatically records noise exposure over time, saving you from manual calculations and tracking in noisy or hard-to-access areas.

Who needs a noise dosimeter?

Workers in loud environments such as factories, construction sites, and mines use dosimeters to prevent hearing loss and ensure safety compliance.

How is a noise dosimeter different from a sound level meter?

A dosimeter is worn on the body for personal noise exposure, while a sound level meter is hand-held and measures noise in a specific area.

How do I know if the dosimeter is working properly?

Check that the screen or indicator light is on and the microphone is securely connected before starting measurement.

What is the Svantek 104BIS?

The Svantek 104BIS is an intrinsically safe, cable-free personal noise dosimeter designed for measuring occupational noise exposure in hazardous environments. It complies with ATEX and IECEx certifications for explosive atmospheres, such as those in mining and petrochemical plants.

How should the dosimeter be worn?

For accurate measurements, the dosimeter should be worn on the shoulder, on the side most exposed to the noise. The microphone must be positioned at least 10 cm from the ear and at least 4 cm above the shoulder, away from clothing.

Does it offer real-time monitoring?

Yes. The 104BIS has a Bluetooth® interface that connects to a smartphone application. This allows users to preview live measurement results without interrupting the worker. The app can also be configured to signal an alarm if preset noise limits are exceeded.

What accessories are needed?

For charging and data transfer, a docking station (SB 104B-1 or SB 104B-5) is required. For analysis capabilities like 1/1 and 1/3 octave band analysis, a separate license may be needed.

What software is used with the SV 104BIS?

The main software for managing, configuring, and analyzing data from the dosimeter is Svantek's Supervisor software. For real-time monitoring on a mobile device, you would use the Svantek Assistant app.
