HS5670B Pulse Integral Sound Level Meter

The performance of the precision acoustic measuring instrument HS5670B pulse integral sound level meter meets the requirements of the JJG188-2002 Sound Level Meter Calibration Regulations and IEC60804 or GB/T17181 standards for Type I sound level meters. The measurement data can be output and transmitted to a computer through an RS232C serial port via a communication cable, achieving real-time communication output of sound pressure level Lp and effective sensing of aircraft noise level measurement calculation. This machine is widely used for industrial noise measurement and environmental noise measurement of various machines, vehicles, ships, electrical appliances, etc. It is suitable for sound testing fields in factories, enterprises, environmental protection, labor health, transportation, teaching, scientific research and other departments.
