SV 104BIS Intrinsically Safe Noise Dosimeter
The intrinsically safe dosimeter is a noise dosimeter designed by the ATEX directive and the IECEx performance specifications. The intrinsically safe dosimeter is typically used in occupational noise measurements in areas such as mines and petrochemical plants where it is necessary to secure intrinsic safety.
The dosimeter is covered by a 3-year warranty and a life-time warranty for the patented MEMS microphone. The intrinsically safe dosimeter uses a new type of docking station for fast data transfer and quick battery recharging.
The SV 104BIS is the newest version (2022) of an intrinsically safe noise dosimeter. Like its predecessor, the SV 104BIS is a cable-free dosimeter and is typically attached to the user’s shoulder, close to the ear using the mounting clips supplied.
Among the unique features of the new model, the software is automatic noise dose calculation, sound pressure level logging, audio recording, octave band frequency analysis, and auto-calibration. The new ATEX dosimeter has an 8GB memory and fast data transfer via new docking stations. The new Bluetooth® interface enables previewing current results on a mobile app.
