3M 7000052884 E-a-r Classic Small Probed Test Earplugs

Product Description

The 3M 7000052884 is a set of small probed test earplugs designed for use with the 3M E-A-Rfit Validation System during individual earplug fit testing. Each plug is modified with an integrated probe tube that allows the fit-testing system to measure attenuation performance on a per-worker basis. These are not rated for hearing protection and must not be used as standard earplugs. Industrial hygienists, occupational health technicians, and safety professionals use these test plugs to validate proper earplug fit as part of a compliant hearing conservation program.

These probed test plugs are used in occupational and industrial settings where OSHA-mandated hearing conservation programs require documented fit testing. The E-A-Rfit Validation System uses a dual-microphone methodology, and these probed earplugs are the required consumable for that process. They are intended for single-use during the fit-testing session and are sold as a case quantity. Safety coordinators and occupational health staff administer the testing process using the accompanying validation system hardware.

Key Features

• Integrated probe tube enables real-ear attenuation measurement during fit testing
• Sized for small ear canals to ensure accurate fit-test results across worker populations
• Compatible exclusively with the 3M E-A-Rfit Validation System
• Single-use design supports hygienic, per-worker testing protocols
• Not rated for hearing protection — for fit-testing use only

Compatibility

Designed for use with the 3M E-A-Rfit Validation System as the required probed earplug consumable for fit-testing sessions. Not interchangeable with standard hearing protection earplugs.

Installation Notes

These test plugs are administered by a trained occupational health technician or safety professional, not a field trade installer. No tools are required. Insert the probed earplug into the worker's ear canal following the fit-testing system's guided procedure. Do not reuse plugs between workers, and do not use these plugs as hearing protection under any circumstances.
