SV-104BIS Personal Noise Dosimeter (Bluetooth-intrinsically safe)

Overview

The SV 104BIS is an intrinsically safe personal noise dosimeter engineered for occupational noise monitoring in explosive and hazardous industrial environments. It features a patented MEMS microphone with a lifetime warranty, auto-calibration via TEDS, and a built-in triaxial vibration sensor. With up to 45 hours of battery life, 8 GB of storage, and IP65 protection, it is built for demanding field conditions. Bluetooth connectivity enables real-time data access via a mobile app, while four independent measurement profiles and optional 1/1 and 1/3 octave band analysis provide comprehensive noise assessment. Fully compliant with IEC 61252, IEC 61672-1 Class 2, ISO 9612, OSHA, MSHA, and ACGIH standards.
