ACO Model 6226 Class 2 Sound Level Meter
This is an integrating-averaging sound level meter appropriate for environmental noise
measurements, equipped with the following measurement functions; equivalent continuous A-
weighted sound pressure level(Leq), sound exposure level (LE), and percentile level(Lx). It is easily
operated to fulfill various functions from measuring the noise of traffic, aircraft and machinery to
quality control and diverse tests. Standard equipment includes an RS-232C interface, and connection
to an outer CPU enables continuous operation.
Measurement results are expressed both by bar graph and numerically on a liquid crystal display.
Further, the wide dynamic range of 100dB eliminates the need for range switching, realizing easier
and more accurate measurements.
