3M 7000052881 E-a-r Push-ins Probed Test Plug

Product Description

The 3M 7000052881 is a probed test earplug designed exclusively for use with the 3M E-A-Rfit Validation System during earplug fit testing procedures. Each plug is modified with an integrated probe tube that allows the validation system to measure sound attenuation at the ear canal, producing real-world fit data for hearing conservation programs. These are not hearing protectors and must not be used as such. Safety officers, industrial hygienists, and occupational health professionals use these probed plugs to verify that workers are achieving adequate protection from their standard E-A-R Push-Ins earplugs.

These test plugs are intended for structured hearing conservation programs in industrial, manufacturing, and occupational health settings. The fit testing workflow requires inserting a probed test plug into the subject's ear, connecting the probe to the E-A-Rfit Validation System, and running the software-guided protocol. Results confirm or flag the fit of the worker's standard earplug. The 7000052881 is sold as a case and is compatible with the E-A-Rfit system's guided fit testing procedure.

Key Features

• Integrated probe tube allows real-time attenuation measurement during fit testing
• Designed specifically for use with the 3M E-A-Rfit Validation System
• Not rated for hearing protection — test and validation use only
• Push-Ins style form factor matches the standard E-A-R Push-Ins earplug family
• Sold by the case with a minimum order quantity of 1 case

Compatibility

Designed for use exclusively with the 3M E-A-Rfit Validation System as part of a formal earplug fit testing protocol. Not interchangeable with standard hearing protection earplugs.

Installation Notes

Fit testing should be performed by a trained occupational health professional or safety officer following the E-A-Rfit Validation System software protocol. Power down or disconnect any audio equipment connected to the system before inserting or removing test probes. Do not insert probed test plugs with excessive force. These plugs are for supervised test sessions only and must not be reused as standard hearing protection under any circumstances.
