【 Product Application 】

Noise spectrum analyzer is not only a general sound level meter to measure the exponential time weight sound level, but also an integral average sound level meter to measure the time average sound level and an integral sound level meter to measure the sound exposure, it can also measure the cumulative percentage sound level (statistical sound level), suitable for all kinds of industrial environmental noise measurement and environmental noise survey measurement. Especially suitable for spectrum analysis of noise for sound level measurement of environmental, mechanical, traffic, ship and other noises; Applicable to industrial environmental protection, construction, health, teaching and research departments.

【 Product Features 】

* Its performance meets the requirements of GB/T 3785 and IEC 61672-2002 for 2-stage sound level meters, JJG 188-2017 standards, and IEC 1260 and GB/T 3241-1998 for octave filters and 1/3 octave filters.

* Has built-in 1/1 octave and 1/3 octave filters. Manual and automatic sweep frequency measurement. Automatic frequency sweep measurement data can be automatically saved 12 groups.

* With integral and statistical functions, a single group of measurement up to 800, the whole time measurement up to 6 days. The stored data can be accessed and printed. The collected data can be checked when the measurement is paused.

* Time meter has three gear options: fast (F), slow (S) and pulse (I).

* Using digital detection technology to replace some traditional sound level meters in the past, stability and reliability are greatly improved.

* Large screen display, clear and intuitive display, dynamic scale display.

* Optional Bluetooth printer for measurement data printing; USB cable, Bluetooth data output, and PC communication.
