Sound Level Meter

HY Series


HY-114 & HY-104 series Digital sound level meter is designed to measure the frequency density of sound a specific area. The meter is able to display the A sound level and C sound level, This meter conforms with the International standard IEC 651-1979 for class I requirement, therefore, the application range is wide: for mechanical test, electronic test, vehicle noise test and vehicle horn inspection.

Main Features

Sound Level Check
Sound Level Meter

It use capacitance for the sound transistor, high capacity amplifier and digital IC chip to collect and calculate the sound level data, the graduation reach 0.1dB in all the application sound range. The structure of meter is simple and compact, it is easy to transport and install. HY-114 & HY-104 is a specific sound level meter for vehicle inspection system, using of RS232 serial port for communication between the meter and computer.

  • Baud rate: 300bit/s (can be designed according to the request of user);

  • Communication way: Full duplex, 1 start bit, 8 data bit, 2 stop bits, have parity bit

  • Communication protocol: Reset the order BCH, start and measure B2H, allow to send to BBH, finish measuring B5H, answer back signal 06H
