Key features

Dual-element, dual-microphone assembly is the key to the system, measuring sound levels inside and outside the hearing protector
Science-based, quantitative testing gives accurate reports of hearing protection
Optional Cloud enables stored centralized data, multiple fit testing systems operating simultaneously across sites, and access restricted to authorized users.
System determines personal attenuation rating (PAR) of individual workers and helps remove measurement, fitting, and spectral uncertainty
Dual-ear design saves time by measuring both ears simultaneously in under five seconds
System tests across 7 standard frequencies (125, 250, 500, 1000, 2000, 4000, 8000 Hz)
Works with a large variety of 3M Hearing Protection Products; earplugs, banded hearing protectors, and earmuffs
Simple, easy-to-use intuitive software
Data can be exported into Excel templates for reports and provide insights to help identify products and techniques that might help improve fit testing efficiency.
Includes Software, Speaker And Impact Resistant Carrying Case.
Free online training and user support
Requires probed test plugs, pods, or cushions

Applications

Engineering and fabrication shops
Power plants and compressor rooms
Mining and quarrying
