FNIRSI FDM-02 Sound Level Meter

The FNIRSI FDM-02 is a precision sound level meter equipped with a color display and a high-quality condenser microphone, enabling accurate measurement of noise levels in various work environments. It supports A/C frequency weighting, FAST/SLOW modes, and a data logging function that generates graphs. Additionally, it allows you to monitor ambient temperature and humidity. All of this makes the device ideal for professional acoustic measurements, monitoring working conditions, and more.

Precise noise measurement

The device uses a condenser microphone, which ensures high sensitivity and measurement stability. The FDM-02 model provides accurate real-time sound level readings, allowing for effective monitoring of noise levels in rooms, workplaces, or public spaces. The easy-to-read display presents current measurement values clearly, facilitating quick analysis of results. Additionally, the meter supports two frequency weighting modes—A and C—allowing you to adjust the measurement method to the type of noise being analyzed. You can also use the FAST and SLOW modes, which enable faster or more stable measurement sampling depending on operating conditions.

Color screen and user-friendly operation

The color display provides a clear image and allows for easy reading of parameters. Additionally, the ergonomic button layout allows you to quickly switch between operating modes and change settings, improving user comfort during both field work and indoor measurements. The FNIRSI FDM-02 also offers a data logging function and a Curve Recording mode, which allows you to visualize changes in sound levels in the form of graphs. This makes it easier to analyze noise fluctuations over a specific period and compare results without the need for manual note-taking.
