Product Description

 This digital meter is a multifunction sound level meter designed to accurately measure sound level of just about anything from sound of level of environment to mechanic, vehicle, ship, loudness of computer fans and other noise with ±1.5 dB accuracy in decibels (dB). In almost all countries, the use of A-frequency-weighting is mandated to be used for the protection of workers against noise-induced deafness and the only weighting mandated by the international standard, the frequency weightings 'C' being optional fitments.

 


A precision device that meets the measurement requirements of Safety Engineers, Health, Industrial Safety Offices and Sound Quality control in various environment. Comply with all the essential requirements of American National Standards set out by American National Standards Institute (ANSI) and the U.S. National Committee, the International Electrotechnical Commission (IEC). Continuous high pressure levels can permanently damage the hearing capacity, even audio speakers. This precision device can help you monitor and maintain healhy environment.
