SV104 BIS

Bluetooth Intrinsically Safe Noise Dosimeter

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.

Proud to be ANZEx certified, the Australian Certification/Recognition System for Hazardous Area Equipment and Services.

New hardware

Patented microphone and faster data transfer

The new SV 104 BIS is equipped with the new MEMS microphone, which offers a measuring range from 53 dB Leq to 143 dB Peak. The list of addons includes new large 8 GB memory and fast data transmission with a new docking station.

New firmware

Options for noise sources recognition

The large 8 GB memory enables the SV 104 BIS to record 1/1 or 1/3 octave bands in real-time and simultaneous audio recording to determine the noise sources and hearing protector selection. Functions can be activated at any time by ordering the activation codes.

Mobile application

Remote connection via Bluetooth® interface

The Bluetooth interface enables current results to be previewed on a smartphone Assistant application without disturbing the workers. The smartphone application signals alarms when the set noise limits are exceeded.

Key Functions

Life-time warranty for microphone – The patented MEMS microphone is extremely robust and is covered by a life-time warranty. The dosimeter itself is also covered by a 3-year manufacturer’s warranty.
Intrinsic Safety – The SV 104 BIS is the intrinsically safe personal noise dosimeter in accordance with the ATEX directive and the IECEx certification scheme.
Occupational noise measurements – The dosimeter is suitable for noise at work measurements in accordance with to standards such as ISO 9612, OSHA, MSHA and ACGIH.
Real-time frequency analysis – The 1/1 octave analysis is often used for the selection of hearing protectors. The 1/3 octave function allows the determination of the influence of high or low frequencies on overall values. Functions can be activated at any time by ordering the activation code.
Triggered audio recording – Audio recording is synchronized with a noise time-history and it can be opened and played back in PC software enabling noise source recognition. Audio recording can be triggered on threshold or time. It can be activated at any time by ordering the activation code.
Time-history logging – The time history logging of results such as Leq, Max, Min and Peak with two simultaneous logging steps is saved on a 8 GB memory.
Built-in vibration sensor – The inbuilt triaxial vibration sensor detects shocks and vibrations that influence noise measurement results and provides the information during the times when dosimeter is not used by the worker.

Supervisor

Supervisor software supports data download, instrument configuration and provides a complete set of tools for determination of occupational noise exposure from noise level measurements in accordance with all standards using TWA and DOSE, such as OSHA, ACGIH, MSHA, ISO 9612.

Assistant

The Assistant is a smartphone application for devices running on Android and iOS platforms, enabling current results to be previewed on a smartphone or tablet as well as controlling the measurement Start/Stop and Markers. The Assistant also signals an alarm when set noise limits are exceeded.
