Product Description
dBadge2IS Intrinsically Safe Noise Dosimeter Kit – 4-Unit Monitoring System
The dBadge2IS Intrinsically Safe Noise Dosimeter (4) Kit delivers professional-grade occupational noise monitoring for flammable and high-risk work zones including oil & gas, petrochemical plants, mining operations, and confined-space environments. This turnkey package combines four shoulder-mounted intrinsically safe dosimeters with a CEL-120/2 acoustic calibrator, multi-bay charging docks, and a rugged transport case—ideal for rotating surveys, crew monitoring, and hearing-conservation compliance programs.
Certified for hazardous locations to Ex ia IIC T4 Ga, Ex ia IIIC T135°C Da, and EX ia I Ma, the dBadge2IS platform provides Type 2 accuracy with advanced diagnostics such as octave-band analysis, event-triggered audio capture, and motion sensing to validate exposure results.
