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.
