SV 102A+ Noise Dosimeters

The SV 102A+ is a Class 1 dual-channel noise dosimeter designed for complex occupational noise environments where a single microphone is insufficient. Its two independent channels enable simultaneous measurement under headsets and at reference positions, or left and right near-ear measurements, capturing asymmetric exposure without requiring repeat shifts. It reports full compliance metrics including Dose (%), TWA8h, and LEX,8h/LEP,d aligned with OSHA, ISO 9612, and NIOSH standards. The dosimeter supports ISO 11904-1 MIRE assessments with the optional SV 25S in-ear microphone, and includes audio recording, 48 kHz sampling rate, and 1/1-octave band analysis. With over 16 hours of battery life, Bluetooth and USB connectivity, and 32 GB onboard memory, it is built for full-shift industrial and aviation noise monitoring.
