The 3M E-A-Rfit 393-1100 Dual-Ear Validation System is a professional-grade hearing protection fit-testing solution designed to take the guesswork out of workplace safety. Many employers ask whether standard earplugs or earmuffs are enough to protect their team, and this system provides clear, quantitative data that shows whether hearing protection devices are actually performing at the required level. Unlike basic field checks, the E-A-Rfit 393-1100 measures real-ear attenuation across a range of frequencies in just seconds, giving safety managers confidence that workers are receiving the protection promised by NRR ratings. For companies in construction, manufacturing, mining, or oil and gas, this is more than just compliance—it is about ensuring long-term hearing health, avoiding costly OSHA citations, and reducing workplace risks. Buyers often want to know if this system is complicated to use; the answer is no. It connects easily via USB to your computer, runs quick tests with microphone-equipped inserts, and delivers instant, printable reports for recordkeeping. By using this system as part of a hearing conservation program, businesses can train employees on proper earplug insertion techniques, identify workers at risk of inadequate fit, and demonstrate due diligence in safety audits. Enviro Safety Products, a trusted supplier of certified PPE solutions, provides the 3M E-A-Rfit 393-1100 with expert support, helping organizations improve safety outcomes while meeting regulatory standards.
