"Noise." Though it is an everyday problem, only experts are engaged in noise level measurements. Is it possible to make noise measurement easy even for beginners... Our simple question has triggered off the creation of a compact, light and easy-to-handle sound level meter with an excellent cost/performance ratio


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 100 dB eliminates the need for range switching, realizing easier and more accurate measurements.

Features
¡Ü Percentile level (Lx) -any 5 selectable values
¡Ü Measure equivalent continuous A-weighted sound pressure level capability (Leq)
Measure environmental noise required for securing occupational health capability
¡Ü Wide linearity range of 100 dB
¡Ü Equipped with an RS-232C function, allows for processing of data by PC
¡Ü Equipped with memory function, allows for storing up to 15,000 bits of data
¡Ü Backite LCD screen for high-visibility and easy-on-the-eye display
¡Ü Excellent cost/performance ratio overpowers comparably priced products
