SVANTEK 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 standard SV 104BIS kit includes a patented MEMS microphone with a life-time warranty, a windscreen with a stainless steel mounting thread. The dosimeter has inbuilt 8 GB memory and a license for PC software (for communication with a PC the optional docking station is required). Each SV 104BIS has its factory calibration certificate.
