I. Summary

        HS6288E Multi-functional Sound Level Analyzer is a portable and intelligent instrument integrated with many functions including integrating, noise stat, noise collection, etc. Innovated with new designs and functions, this type can meet kinds of meterage requirements. All performance index are in line with IEC61672 and JJG188—2002 examining regulations.

This meter has a large LCD screen. It can store up to 500 groups of single data and 4 groups of punctual data and all data can be stored for long-term. Through its inner-installed RS-232C interface, the data can be uploaded to the computer or typed out by mini-printer on the site or afterwards.

The meter is structurally compact and slinky with multi-functions and highly automated. It can be used in metering of environment noise and industrial noise such as labor protection, industrial sanitation, machinery, vehicles, electrical appliance.
