HS5660B (High Low) Precision Pulse Sound Level Meter

1、 Application scope and characteristics:
The HS5660B (high/low) precision pulse sound level meter is a low (high) measurement lower (upper) limit portable acoustic measuring instrument, which reads out the measurement results simultaneously from an electric meter and a liquid crystal display. It can be used to measure and analyze environmental, machine, vehicle, motor and other noise, as well as for building acoustics, electroacoustic measurements, etc. Especially its pulse characteristics can accurately measure impact sound and short duration noise, such as gun sound, stamping machine sound, explosion sound, typewriter noise, etc. It can also be combined with HS5721 type 1/1 octave band filter or HS5731 type 1/3 octave band filter to form a portable spectrum analyzer with easy operation. Widely applicable to the needs of environmental protection, factories, schools, scientific research and other departments for measuring and analyzing low (high) noise. The JJG188-2002 Sound Level Meter Verification Regulations and IEC61627 Sound Level Meter standards require Level 1 performance.
