Applications
The precision sound level meter is a multi-functional sound level measuring instrument. It can not only be used as a general sound level meter to measure exponential time weighted sound levels, but also complies with the requirements of GB/T 3785 and IEC 61672-2002 standards for Class 1 sound level meters. performance requirements, and also meets the JJG 188-2017 standard. This equipment is suitable for noise measurement in various industrial environments and environmental noise census measurements. It is especially suitable for sound level measurement of various types of noise from the environment, machinery, transportation, ships, etc. It is also suitable for industrial environmental protection, construction, sanitation, teaching and scientific research. needs in many fields.
Features
This precision sound level meter has the following features:
Provides three time weighting gear options: fast (F), slow (S) and pulse (I).
Digital detection technology is used to replace the traditional sound level meter, thereby significantly improving the stability and reliability of the instrument.
Equipped with a large screen display, the information is presented clearly and intuitively, and it also supports dynamic scale display.
