HY114 Series Sound Level Meter
The HY114 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.
Automatic measurement and data processing of noise can be realized by computer controlled instruments It has good electromagnetic shielding, anti-collision and anti-extrusion functions, and is more suitable for use in high-temperature and high-pollution environments.
Passed the type evaluation test, certificate number: 2019S125-43.
