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, an auto-calibration feature and TEDS memory that stores the calibration information in the microphone itself.
The SV 104 BIS Bluetooth interface enables our Assistant application to preview current results on a smartphone or tablet. The smartphone application also signals an alarm when the set noise limits are exceeded.
New hardware – Patented microphone and faster data transfer – The new SV 104 BIS has a MEMS microphone, which offers a measuring range from 53 dB Leq to 143 dB Peak. The list of add-ons 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 simultaneously record audio 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.
Lifetime warranty for microphone – The patented MEMS microphone is highly robust and is covered by a lifetime 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 standards such as ISO 9612, OSHA, MSHA and ACGIH.
Real-time frequency analysis – The 1/1 octave analysis is often used to select 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 in an 8 GB memory.
Built-in vibration sensor – The built-in triaxial vibration sensor detects shocks and vibrations that influence noise measurement results and provides information when the worker does not use a dosimeter.
