3M 3M™ Skull Screws™ Probed Test Plugs

Overview

The 3M™ Skull Screws™ Probed Test Plugs are designed for use with the 3M™ E-A-Rfit™ Dual-Ear Validation System to accurately measure the effectiveness of hearing protection. These test plugs replicate the fit and feel of standard Skull Screws earplugs, featuring a unique screw-like design for easy insertion and a secure fit. Integrated probe tubes allow for precise sound level measurements inside the ear canal during fit testing, helping ensure workers receive proper hearing protection. Ideal for training and compliance in occupational hearing conservation programs, these plugs are reusable for testing purposes but not intended for actual hearing protection use.
