Hazardous Location Dual Protection (ExDP) Headset for Communication in Extreme Noise Environments
Sensear has addressed the critical need for double hearing protection in extremely high-noise and hazardous environments with the development of the SM1P-ExDP. This innovative headset integrates Sensear's advanced SENS® communication capabilities, providing users with face-to-face communication and 360° situational awareness while maintaining hearing protection in extreme noise and hazardous environments where exposure levels may exceed 95 dB(A).
Building on the proven design of the SM1P-Ex headset, the SM1P-ExDP incorporates a unique dual-protection feature, integrating earplugs into the earmuffs and incorporating advanced SENS® Technology so users can effectively communicate without compromising hearing safety. With ATEX and IECEx certifications, the SM1P-ExDP headset meets stringent safety standards for use in explosive environments, offering peace of mind to users in hazardous workplaces.
The SM1P-ExDP headset offers a comprehensive solution for users operating in extremely high-noise and hazardous environments, such as those involving explosive chemicals, fuels, and combustible powders. With its dual-protection feature, advanced communication capabilities, and robust design, the SM1P-ExDP headset is the top-tier solution for ensuring safety and efficiency in challenging ATEX workplace conditions.
