HS5670XB Type Noise Automatic Measurement and Analysis SystemDetailed product description：

The HS5670B pulse integral sound level meter is a precision acoustic measurement instrument innovatively developed based on our leading product HS5670XA noise automatic measurement system. It has the characteristics of large dynamic range, large screen LCD digital display, automatic measurement and storage of various data, etc. The external filter can automatically perform 1/3 or 1/1 spectrum analysis. The measurement data can be output and transmitted to the computer through the RS232C serial port via communication cable, realizing real-time communication output of sound pressure level Lp and effective sensing and calculation of aircraft noise level Lepn. Compliant with JJG188-2002 Sound Level

One Application scope and characteristics:
The HS5670XB noise automatic measurement system is a precision acoustic measurement instrument innovatively developed based on the HS5670XA noise automatic measurement system. It has the characteristics of large dynamic range, large screen LCD display, and automatic measurement and storage of various data. The external filter automatically performs 1/3 or 1/1 spectrum analysis. Through the RS232C serial port and matching printer, the measurement results and spectra can be automatically printed out. The measurement data can be output and transmitted to the computer through the interface communication cable, realizing real-time communication output of sound pressure level Lp and effective sensing of aircraft noise level measurement calculation using Lepn. Compliant with JJG188-2002 Sound Level Meter Verification Regulations and IEC60804 or GB/T17181 Standard Type I. It can be 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.
