FNIRSI FDM01 decibel meter sonometer

The FNIRSI FDM01 is a compact decibel meter that combines noise measurement in the 30-130 dB range with simultaneous temperature and humidity monitoring. The device is equipped with a sensitive condenser microphone, a 2.3" color VA display with backlight, and a 600 mAh lithium battery charged via USB-C. With a fast response time, MIN/AVG/MAX measurement modes, a light alarm, and two detection modes (FAST/SLOW), the FNIRSI FDM01 is ideal for use in offices, construction sites, transport, production halls, and public spaces.

Precision measurement microphone

The 6mm condenser microphone is characterized by high sensitivity and a fast response time. The use of nickel-plated steel, a three-layer conductive structure, and silicone seals effectively isolates interference and ensures reliable results even with sudden volume spikes. The FNIRSI FDM01 decibel meter allows you to choose between fast (1 s) and slow (1.25 s) measurement modes. This allows you to adapt the data recording method to dynamically changing conditions or obtain a more stable result in the case of constant noise sources.

A-weighting measurement

The device uses an A-weighted characteristic, which reflects the sensitivity of the human ear to different frequencies. It measures within the 31.5 Hz – 8.5 kHz range, allowing for a reliable assessment of environmental noise levels in accordance with standards.

Light alarm and value lock

The FDM01 model signals when a set sound threshold is exceeded with a red alarm LED. It also allows you to display only the minimum, average, or maximum values, making it easier to document results. The "HOLD" function freezes the current reading on the screen.

Easy to read screen and durable housing

The 2.3-inch VA display clearly presents all data, even in bright conditions. The ABS housing and silicone buttons increase the device's durability in field and industrial environments. The design with a soft windshield reduces the impact of environmental interference on measurements. The 600 mAh lithium battery eliminates the need for batteries. The device is charged via a USB-C port, simplifying operation and reducing operating costs.
