Brief introduction: HS6298 type multifunctional noise analyzer is a sound level meter right time measurement index of general sound level meter, and can measure the time average sound level of the integral average sound level meter and measuring the integral sound exposure sound level meter, it can also measure the cumulative percentage sound level, statistical sound level), noise dose, its performance in accordance with GB/T3785 and IEC61672-2002 standard requirement for 2 levels of sound level meter, sensitivity to rf fields belong to class X. The instrument adopts advanced digital detection technology, which has the advantages of high reliability, good stability and wide dynamic range. This instrument adopts the 128 * 64 dot-matrix LCD with background light, according to all the Chinese interface, shows rich content, the operating interface using the menu, there are Chinese prompt functions, user operation is simple, the battery power supply, the measured results can be stored in the instrument for a long time, through the built-in RS - 232 interface at the scene with the micro printer to print out or sent to a computer to deal with.
