SVANTEK Class 1 Dual-Channel Noise Dosimeter SV 102A+
SV 102A+ is a Class 1 dual-channel noise dosimeter for complex environments where exposure differs ear-to-ear or under headsets. Two independent channels let you measure under a headset and at a reference position (e.g., shoulder) at the same time, or left/right near-ear simultaneously, capturing asymmetric exposure without repeat shifts. It reports compliance metrics including Dose (%), TWA8h, and LEX,8h / LEP,d for OSHA/ISO-style programs. Ships ready to use with core accessories for immediate deployment.
For MIRE (Microphone-in-Real-Ear) assessments under headsets/helmets, the SV 102A+ supports ISO 11904-1 methods. MIRE requires the optional SV 25S in-ear microphone and enabled 1/3-octave bands to recalculate doses from in-ear levels. A high 48 kHz sampling rate preserves close-to-ear transients and high-frequency content. Investigations are accelerated by audio recording (for playback and source verification) and 1/1-octave analysis for hearing-protector selection. If you need a single-channel wireless model, the SV 104A adds Bluetooth® for app-based monitoring; for hazardous areas, SV 104IS kits are available.
