EXAIR Digital Noise Level Meter – 5 Ways to Reduce Industrial Noise & Comply with NOM-011-STPS-2001
Long-term exposure to high sound levels can lead to hearing loss, operator fatigue, reduced productivity, and safety risks. Implementing reliable EXAIR noise level detection systems allows companies to monitor workplace noise conditions and take corrective actions before noise exposure becomes dangerous.
The unit provides accurate noise level measurement capabilities through a simple and easy-to-use handheld design. It measures sound levels between 35 dB and 130 dB and includes both A and C weighted measurement scales for evaluating different industrial sound conditions. These measurement options help maintenance personnel and safety managers analyze noise levels accurately across multiple applications. One of the key advantages of this sound level meter for industrial use is its ability to operate in dynamic industrial environments.
The instrument includes fast and slow response time settings that allow users to measure both stable and rapidly changing sound conditions. The fast response setting captures sudden noise variations, while the slow response setting provides stable readings for continuous monitoring applications. The integrated Max Hold function continuously records and updates the highest detected sound level during operation. This feature is especially useful for identifying the loudest areas in industrial facilities and evaluating noise generated by compressed air equipment, machinery, and manufacturing processes.
Digital noise monitoring EXAIR technology is commonly used in manufacturing plants, automotive facilities, packaging operations, food processing plants, and metalworking industries. Companies implementing these systems can reduce workplace risks, improve employee safety, support hearing conservation programs, and create safer industrial environments.
